Facts about gold

Gold and its alloys

Gold quality is usually defined by karat, with each karat representing 1/24 of the amount of pure gold in an alloy ( as measured by weight ). Thus the higher the karat, the greater the proportion of pure gold there is. the remaining content of an alloy consists of assorted elements that combine to strengthen, provide color, or in a few cases, act as correctives for unwanted properties of other alloying elements.

Pure gold in its natural state is rich, almost buttery yellow, but when alloyed, it can be produced in a range of other colors. Yellow, white, green, and rose/pink golds are available as bulk metals, which are uniform in color throughout an alloy. Some blue and purple golds are also bulk metals; they are very brittle and not commonly used as jewelry alloys.

Chocolate, black and some other colors of gold are often products of surface treatments and coloring. There are also blue, and black golds that are the products of oxidation reactions rather than coating. These alloys contain, cobalt or iron, which greatly reduces ductility but also colors the gold during heat treatment.

The most frequently used white gold alloys are created with nickel or palladium. Nickel has been the typical bleaching agent for white gold, but widespread nickel sensitivity is changing that. Because of the sensitivities, nickel content is closely regulated in the Europe Union. The wider effect is that nickel content of gold alloys has been reduced. However, the less nickel there is in an alloy, the more yellow gray the alloy will be, and so rhodium plating(about every six months, replating) is used to make the alloy appear white. Degree of whiteness-or, more accurately, paleness-for white gold has not been standardized. Guidelines for the disclosure of rhodium plating to consumers have also not been formalized.  Alternatives to nickel white gold alloys have been and are being developed. Palladium-white golds can be completely free of nickel; these white golds are also likely to be more expensive than the nickel whites.

Gold price calculator

Gold market price was $1275 per ounce. One ounce has 31.1 grams

$1275* 31.1 =$40.99 price of pure gold (99.95%)


Jane had 50 grams of 18K scrap gold wanted to sell , and she wanted to know how much it brought her.

$1275 * 31.1 grams = $40.99 pure

$40.99 x 75%(18k) = $30.74

$30.74 x 50 grams = $1537

$1537 is the amount of her 50 grams of 18K gold.


The value of gold is determined by its weight, but keep in mind that
jewelers use a different scale to measure gold weight called the Troy
ounce. U.S scales measure gold using grams per ounce, for example 28
grams per ounce, while in Troy ounces this would be 31.1 grams per
Troy ounce. There’s another system called pennyweight (dwt) that’s
commonly used amongst jewelers. In pennyweight the equivalence would
be 1.555 grams per pennyweight. So now that you understand the scale
for measuring gold, you should stay alert when a dealer decides to
weigh your gold by gram instead of pennyweight or Troy ounce. This is
a shady way for dealers to pay you less for more of your weight of
gold. The more you know, the better.



How to buy a perfect diamond

Buying a diamond has never been easier. But how to buy a perfect diamond is not easy as you think. Each one of us has been spending hours of  hours going through online dealers searching for a perfect diamond, like looking for a needle in a haystack. And not a guarantee that we’ll find the right one. The best way to search for a perfect diamond is to ask  for the referral from friends and families or online referrals, such as diamonds review companies.  Some of these companies are really helpful when looking for diamond onlines.

Focus on workmanship of the diamond, which is the Cut and the clarity- where the inclusions located. Look at the certicate of the diamond(plotting).

Most of us probably have some ideas about diamonds, is not completely blank like about ten years ago. There are so many educational blogs about diamonds online just a click away. We most likely know about the 4Cs; Carat, Cut, Color, and Clarity.

round1.09 Carat HSI1


1.09 H SI1 XXX None,$5200 Sold by James Allen


 1.09 H SI1 XXX None,$5652 sold by Blue Nile

These two diamonds are almost identical, can be used as a matched pair for stud earrings.  As you can see the one from James Allen sold for $5460 and the other from Blue Nile sold for $5652. Both are eye-clean diamond. And if you are out there looking a diamond with the budget 5k to 6k to spend , you would want to go with the one from James Allen has better clarity but only if you don’t mind Fluorescence. If you prefer without Fluorescence then you should go with the one from Blue Nile.

Color and Clarity grades are not absolutes, they are ranges. Assuming you about to purchase a round cut diamond H color , VS2 clarity. Is the ‘H’ closer to the ‘G’ or ‘I’ ? Is the VS2 just miss being a VS1 or SI1? All these factors make a big difference in price. Is not simply a matter of how much the H VS2. There’s a variation in how beautiful a diamond appears if ranked at the high-end of a cut grade versus one at the low-end of the same cut grade, it could be  a 35% differential.
 round1.04 Carat GVS2
 1.04 G VS2 X.X.X
round1.05 Carat GVS2
1.05 G VS2 X.X.X
These two stones above are sold by James Allen, and both are G color and VS2 clarity, but the 1.03 is a better VS2 with excellent cut and excellent symmetry and very good polish,so you want to go with that one instead of the  lower VS2 1.05 excellent cut, polish,and symmetry.
Color and Clarity are not the major considerations in pricing a diamond. The cut plays the biggest role, more than any other factors, cut determines beauty and brilliance. A ‘D’ color even a Flawless diamond may lack beauty and brilliance due to poor cutting. To purchase a diamond that both beautiful and brilliant, search for a stone that’s well proportioned, then the balance color, clarity, and size with your budget. Each color and clarity grade sets a range of prices that overlap. Cut alone may cause as much as 55% variation in price for a specific color and clarity grade. Inherent shortcomings in the diamond may add another 25%. Two diamonds with the same color and clarity and weight could vary in price as much as 70%.
 round1.03 Carat GI1
1.03 Excellent cut G color, I1 clarity, $3190
 round1.02 Carat GI1
1.02 Excellent Cut, G color, I1 clarity, $3310
Obviously, you want to go with the first one 1.02 excellent Cut and also the inclusions blended in made it an eye clean stone, unlike the 1.01 that has black inclusions, it’s very noticeable.
As a smart buyer  you can not purchase diamonds by the numbers alone. We encourage customers to look at the products, (with a 360 degree view), not the Paper/Certificate or let a professional helps. There are so many factors not reflected on the a certificate, tinge of color or the life of stone that make a difference in price. A  tinge of brown, which is why it’s worth much less. The same can be said for the purity. Within a clarity grade, there could be a big price gap between the lowest and highest in the range. Two VS or SI1 grades; one with the black crystal inclusion in the center of the table the other with one small crystal and feather on the side could be more than a 10% difference in price, but it doesn’t mean the cheaper stone is the better deal.

Most popular engagement rings

Solitaire Engagements

Any mounting with single center stone is considering solitaire. Doesn’t matter prongs, bezel, or channel set. Engagement rings don’t have to be diamonds, you can select any stone that you like to be set into your engagement ring. Diamond solitaire engagement is the most popular of all times, simple yet classic and

Accented diamond engagements

It’s just like solitaire but just add diamonds on shank, and can be going half, three quarter, or all way around(eternity)the shank is fine as preferred. The 6.5mm round Burmese ruby is eagle claw set, and the color is pigeon blood red, high demanded color for ruby.The ruby ring accented diamonds go half way is perfect for resizing when needed. The contrast colors makes the ruby stand out  But go all the around is problem when sizing. Usually, for half and three quarter way are have no problem when sizing up to 2 sizes(each ring is different), but for sizing down have to be extremely careful because it makes diamonds loose. After sizing down all diamonds have to be tightened, please let your jeweler knows.



Single halo engagements

Center stone can be any kind of gemstones. Diamond is the most popular of course then Sapphire and ruby. These single halo just blend in with the center and make it look like one single center stone from the distance. All these custom made pieces below were made to fit the center perfectly. The diamonds make the the heart-shape stone stand out even more. The heart-shape blue sapphire not only stunning but also quite fitting for an engagement ring, and furthermore is certified by GIA, The World’s Foremost Authority in Gemology. The color of the sapphire is deep  blue, royal blue, No heat. The mounting itself is well-proportioned. The other two mountings are also custom made. The one with the split shank, center is framed by full cut round diamonds in single halo design.

How to calculate the price of a diamond

1. The size of diamond (carat weight)

Carat weight is the measurement of how much a diamond weighs. A metric ‘Carat’ is defined as 200 milligrams. Each carat can be subdivided into 100 points. This allow very precise measurements to the hundredth decimal place. the weight of diamond below one carat can also be described by its ‘points’ alone. Example, a diamond that weighs 0.49 carats could also be referred to as a ‘forty-nine pointer’. Diamond greater  than one carat are expressed in carats and decimals. A 1.03 carats stone would be called/described as ‘one point oh three carats’.

2. Color ( GIA D to Z range )

Diamond Color

The color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, and consequently, a higher value. Based on The GIA Color Grading System measures the degree of colorlessness by comparing a stone, under controlled lighting and precise viewing conditions, to masterstones of established color value. Many of these color distinctions are so subtle that they are visible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.

round1.06 Carat EVS2GIA 1.06 E VS2

round1.04 Carat GVS2GIA 1.04 G VS2

The GIA color scale begins with D for colorless and continues through the alphabet to Z light yellow, brown, or gray. A diamond’s color grade is based on its tone and saturation, and requires an assessment of its absence of color. This means that the less yellow, brown, or gray there is in a diamond, the higher its color grade.

Each letter on the scale represents a narrow color range, not a specific point. And each masterstone marks the highest point or least amount of color in the range. A diamond with slightly less color than the I masterstone is considered H color, one with slightly less color than the H masterstone is considered G color and so on. Five diamonds graded H can have five very slightly different amounts of color, but they all must have less color than the I masterstone, and more color than or an equal amount of color to the H. If a diamond has less color than an E masterstone, it’s a D. This means there is no need for a D masterstone.

3. Clarity ( Flawless to I3 range )

The clarity grade characteristics in diamonds come in an endless variety of combinations, so there can never be one single description that automatically describes a grade. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions‘ and external characteristics called ‘blemishes‘.

Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as these affects the overall appearance of the stone. Many inclusions and blemishes are too tiny to be seen by anyone than a trained diamond grader. To the naked eye, a VS1 and the SI2 diamond may look exactly the same, but these diamonds are quite different in terms of overall quality.

round1.01 Carat FI1

round1.01 Carat FI1

round1.01 Carat HI1

round1.05 Carat HI1

round1.52 Carat FI1

These five diamonds above were graded GIA as I1 clarity from James Allen 

Five factors determine the overall impact that an individual clarity characteristic has on a stone’s appearance and grade. Those factors are;

A. Size–>size has a lot to do with how easy it is to see an inclusio. Generally, the larger and more visible an inclusion is , the lower the diamond’s clarity grade will be. And must consider the size of the inclusion in relation to the size of the diamond. In a diamond with inclusions of different sizes, one or two of larger inclusions usually establish the grade. If there are also smaller inclusions, they seldom affect the clarity grade.

B. Number–>when all other factors are equal, the more inclusions or their reflections you see face up at 10x, the larger the effect on the clarity grade. Because a diamond’s facets act as mirrors, inclusions might be reflected multiple times. Even when a small inclusion is only somewhat easy to see, reflections can make it more apparent. Remember that grades are set by counting them. A diamond with a number of minute pinpoints can still qualify as VVS. On the other hane, a single large, black, or centrally located included crystal could drop the grade into VS, SI, or even I clarity.

C. Position/location–>Inclusions are most visible when they are directly under the table. Inclusions under crown facets or near girdle are usually difficult to see that is why you have to inspect the stone from several angles to find all its characteristics.

D. Relief–>relief is the contrast between an inclusion and its host gem. Relief can vary from high, or more apparent, to low, or less apparent. Usually, the more an inclusion differs in brightness, darkness, or color from its host, the more visible it is and the greater its impact on the clarity grade.

E. Nature–>nature refers to the type of characteristic and its effect on the diamond. Inclusions have more impact on clarity than blemishes. Graders must sometimes refine the clarity grade to a higher or lower level because of nature. Such as, internal graining is an optical irregularity that has far less impact on a diamond’s clarity that a physical break of similar size and appearance. A minute feather would have less impact on clarity than an included crystal of similar size and appearance due to its superficial nature.

Another factor to consider is an inclusion’s potential risk to the stone. Generally, a stone with significant durability problems would not survive the friction and the pressure of the cutting process, so durability rarely affects clarity. However, very deep feathers that extend from the crown to the pavilion, or that penetrate one-third of the way or more into the diamond, pose durability concerns and can lower the grade.

4. The make(Cut grade; Excellent, Very Good, good, Fair, Poor)

The cut plays the biggest role, more than any other factors, cut determines beauty and brilliance. A ‘D’ color even a Flawless diamond may lack beauty and brilliance due to poor cutting. To purchase a diamond that both beautiful and brilliant, search for a stone that’s well proportioned, then the balance color, clarity, and size with your budget. Each color and clarity grade sets a range of prices that overlap. Cut alone may cause as much as 55% variation in price for a specific color and clarity grade.

The cut grading system for standard round brilliant cut diamonds D to Z colors. Standard round brilliant diamonds are evaluated for one of the five possible cut grades: Excellent, Very Good, Good, Fair, poor. Cut grade is determined from a combination of measured parameters and visual observations.

Table size percentage, Pavilion Angle, Crown Angle, Lower Half Length percentage, Star Length, Girdle thickness %, Culet Size , and the degree of painting and /or digging out are all measured. Symmetry, Polish, Girdle Thickness. The combination allows the face-up appearance ( brightness, fire, scintillation, especially pattern seen when viewing a diamond

Excellent cut 1.10  F I1round1.1 Carat FI1

Very good cut 1.01 F I1round1.01 Carat FI1

   Good  Cut    1.20 F  I1round1.2 Carat FI1

size and shape are two aspects of cut that can influence diamond color. The larger a diamond is, or the deeper its pavilion, the farther light can travel in it. This increases the amount of selective absorption that takes place and often leads to a richer, or more intense color.

5. Does it have fluorescence (very Strong, Strong, Medium, Faint)

Fluorescence is the emission of visible light by a material when it is stimulated by ultraviolet UV rays. About 1/3 of diamonds emit some degree of fluorescence. This means that fluorescence, if present, can be one of a diamond’s identifying features. When evaluating a diamond , whether it’s in the D to Z  or the colored diamond range, the grader check to see if it fluoresces.

On the GIA Laboratory Diamond Grading Report, the fluorescence entry is a description, not a grade. The terms used for describing fluorescence are None, Faint, Medium, Strong, and very strong. If the fluorescence is Medium or strong, the grader also notes its color, so a stone might have Medium yellow or strong blue/white fluorescence.

To determine fluorescence, the grader places the diamond a short distance away from a source of long-wave UV radiation. If there’s no obvious fluorescence, or if the fluorescence is insignificant, it gets a classification of None. If a diamond does emit some light, the next step is to describe the degree of fluorescence. It takes experience with seeing many diamonds with varying degree of fluorescence before a grader can accurately describe fluorescence.

Example: if you’re purchasing a 1.03 carats G color and VS2 clarity, list price for 1.00 ct to 1.49 cts is $7900 per carat, you would take the 1.03×7900= 8137. If you purchasing a 1.34 carats would be 1.34×7900=10586 and the discounts between 5 to 20 percents depending the market conditions, availability and the demand of that diamonds.  When you’re ready to buy, contact us we can help you get the most out of your money or visit James Allen

What is an electronic diamond tester?

In today’s diamond market, synthetic diamonds are often hard to distinguish from real stones. Synthetic materials, like cubic zirconia and moissanite, both create an imitation stone that looks much like a real diamond to the naked or untrained eye. Diamond buyers and sellers have come to depend on electronic diamond testers to ensure the diamonds they purchase are genuine. Diamond testers are really useful in checking for diamond imitations. Synthetic stones, such as strontium titanite, or zircon, tend to have high refractive indices. The high refractive indices make the imitations look more like a real diamond than those with low refractive indices, such as glass. The higher the refractive index, the harder it is to differentiate between synthetic and real diamonds. People with no knowledge of gemology often find it very difficult to identify these imitations, making an electronic diamond tester a useful tool. 

There are many diamond testers available on the market. Below is a list of our favorite testers: 

The Presidium DiamondMate-C offers fast, easy and reliable testing. Visual lights and audible beeps make reading results seamless and easy to understand. The thermal conductivity method allows for reliable, precise results. The Presidium DiamondMate-C requires very little battery consumption, allowing for prolonged use without worrying about battery life. As an added feature, this diamond tester also has a built-in metal detector that beeps when it comes in contact with metal.

Precision retractable probe-tip with enhanced durability, and indestructible polycarbonate housing with molded rubber base make this diamond tester impact resistant. The tester is powered by a micro-USB or with the included rechargeable NiMH batteries.  

How to use a Diamond Tester

Most testers are easy to use. They work by pressing a metal point against a facet of a stone. The metal point heats up. The tester then detects the rate at which heat transfers through the stone. The way heat transfers through a synthetic material, such as cubic zirconia, greatly differs from how it transfers through a real diamond.  The diamond tester will then give a signal that indicates if the stone is genuine or not. Using a diamond tester is fairly simple, but below you can find a list of tips that will be helpful if you’re using a tester for the first time: 

  1. Most important, the stone must be cool before using the diamond tester. A person’s body temperature can warm a diamond sufficiently just by wearing it. This will affect the reliability of the test. If a genuine diamond is too warm when tested, it may result in an inaccurate reading. If the stone was being worn, remove the stone from the person’s body and allow it time to cool. You can also cool down the diamond by spraying it with an upside-down can of compressed air, or placing it under cold water and wiping it dry prior to testing.

Gemlogis Lapis One | new product sold by Stuller  

Gemlogis Lapis One Electronic Diamond Tester
  1. An adjacent diamond cannot be tested right away. You cannot get a reliable reading if you consecutively test stones that are adjacent to one another, because the electrical charge transfers heat through the entire stone, as well as any adjacent stones. Since the adjacent stones are now warm, the tester may give a false reading.  After testing the first stone, allow time for the stones to cool, and then repeat the process for all adjacent stones.
  2. Stones cannot be retested immediately. The stone will still be warm from the initial testing and needs time to cool down. 
  3. Be sure the pointer is not touching metal. Electronic diamond testers will not work properly if the point is touching any metal, such as a bezel edge or a prong. Be sure the point is not in contact with metal. Some models have a metal detector to warn you of nearby metal.
  4. Keep the battery well charged. If the battery is not well charged, you might not get an accurate reading. Most models now have an indicator that tells you if the battery is insufficiently charged, but remember to check before you begin testing.

When is the best time to buy a diamond?

Diamond is forever and so precious. Diamond is a girl’s best friend. Whenever you think you are ready to buy a diamond do your homework gather all information before buying.  All of us want to buy things at the lowest price possible, it doesn’t matter what it is. But make no mistake we want to buy it right. Based on my experience, the best time to buy a diamond is around summer time( mid June to mid August). Researched and based on the current market condition. This’s the time when people planning for vacation, traveling. no one wants to spend money on diamond jewelry.  It’s considering slow for the dealers and the best time for some people that are looking to shop for diamonds.  Avoid Valentine’s day, Mother’s day, Black Friday , Cyber Monday, and Christmas. Those are the time that diamond dealers and jewelers make the most from consumers.


Give yourself a good amount of time to shop for diamonds, please do not rush to buy and be flexible, what i mean by flexible is, let’s say you were thinking to buy a 1 carat G color and VS2 clarity for your girlfriend soon to be your fiance, and the dealer you know doesn’t have that specific stone in hands , he/she only have the 1 carat H color and SI1 (which is one color and one clarity grade lower), so go for it, like that you can definitely get better deal rather than the dealer has to find the G color and  VS2 clarity for you. Its also save you some money too, because the H color and SI1 clarity list price is lower than the G color and VS2 clarity, considering all other factors are the same. Diamonds never go out of season. Unlike electronics or vehicles, for instance like a new car dealer would give you discount for the last year models. Diamonds don’t have seasonal sales or whatsoever. Jewelry prices never at their lowest price, they only make you think you get better deal.  Right now, economy is terrible at the moment, if you haven’t noticed. The stores are hurting.

At any time, even during a sale, at whatever store you are shopping at, or online if you see something you really like, ask if it is their best price. Especially at the present time with the economy being so bad. They will say yes most of the time if the price you offer is reasonable, they don’t want to miss the opportunity to sell to you. Be smart and shop around and find out why some diamonds are priced so much higher than others. The reason is the quality of the diamond and you should learn how to distinguish a quality stone from a piece of junk. Also, stay out of department stores and discount stores, such as Costco. They don’t know about diamonds. They are only salespeople. You can find out more info here or if you need help find the best diamond engagement ring for your love ones, we can help you.

History of diamonds

Diamond History

To qualify to be a precious stone, it must be transparent, sufficiently hard and sufficiently rare. Because the diamond fully meets all of these criteria, it is the king of all and precious stones. Its special position in the realm of precious stones is the reason why a certain myth has always surrounded the diamond. The myth of the diamond and its relative scarcity are reflected in its high price. The myth, however, is not a phenomenon of the modern era. It already existed in ancient times. Although we will never know for sure when the first diamond was discovered, we do know where it was first found, India, which was the only source of supply until the 18th century. The diamond was first mentioned in a book that was not discovered until 1905 and that was written by an ancient Indian political philosopher, who lived about 300 BC. The book reports that there was a lively trade in diamonds at the time and that taxes even had to be paid on diamonds transactions.


The beautiful shape of the crystal and its transparency were highly valued at the time. All diamonds that were regarded as very beautiful, such as clear specimens having typical perfectly formed octahedron shape for instance, belonged to the rulers and remained in the country.



Other stones were exported, yet what motivated people to own or sell a products for a high price that they could not process or really use? It must have been mystical magic emanating from a beautiful, clear diamond that held people in its spell. The diamond was fascinating not only because it was beautiful. The fact that it is the hardest of all precious stones but also made it an object of desire.



In ancient Greece, people regarded the legendary stones that were imported from a faraway country as “splinters of stars fallen from the heaven”.  According to tradition, they are even “tears of the gods that have fallen to the ground”.  To give the expression to the hardness of the diamond, the Greeks called it “Adamas” the invincible. Our present-day word “diamond” is derived from this term. It was discovered in the 15th century that the hardness of the diamond is not the same in all axes.



This phenomenon is called “hardness anisotropy”.  This anisotropy means that the hardness in very specific directions is minimally less than in others, making it possible to cut diamonds. Cutting allows us turn insignificant rough stones into magnificent faceted diamonds, further enhancing the magic of the myth surrounding them. Friedrich Mohs, who died in 1839, was the first to successfully express the tremendous hardness in comparison with other minerals. He developed his 10-level hardness scale, on which the diamond is the only mineral that is at level 10.

Following the diamond, ruby and sapphire are level 9 in its corundum varieties. Application of a method in 1897, in which the volume loss of a diamond was measured when a given amount of abrasive was consumed, yielded impressive results. The diamond, although only one level higher on Mohs hardness scale, is 140 times harder than corundum. This corresponds to  the total difference between level i to 9 on the Mohs hardness scale. So what the ancient Greeks believed in is in fact true. the diamond is tremendously hard and is actually the hardest naturally occurring material.

Occurrence,  from carbon to rough diamond

The formation of precious stones vary greatly depending on the type of mineral. As an absolute precondition, however, particular matter in the earth’s crust must combine in certain proportion when exposed to very high temperature and pressure, and they must then cool off within a certain time, forming crystals. The probability that all of these  conditions are present to the required degree is imperceptibly small, making precious stones relatively rare. Despite that fact that no other mineral has been studied in more detail than diamond, it has stubbornly resisted all attempts to reveal the ultimate secrets surrounding its creation.

Diamonds made up only one element, namely carbon. Yet in addition to diamond, graphite is also a form of pure crystalline carbon. What gives diamond its unique hardness is its tight atomic lattice. The diamond’s crystal structure belongs to the cubic system. The diamond is usually an octahedron (8 surfaces) and less often has shape of a cube (6 surfaces) or a rhombic dodecahedron ( 12 surfaces). Severals theories, which have not been disproved, exist concerning the diamond’s exact crystallization process.

These theories are all based on laboratory experiments for producing synthetic diamonds. The best known theories is as follow. The diamond forms a as crystal in a molten mass,namely cooling liquid magma. The initial temperature for this process is about 1300 degrees centigrade, and the pressure is about 70.000 atm. Ambient conditions of this type only occur at the depths of 130-200 kilometers below the surface of the earth in active volcanoes.  diamond chemical equation for creation process is as follow : 2FeS+CO2=FeO+S2+C = Diamond. Other theories use different values for temperature and pressure to some extent and, as a result, for depth. The chemical equation can also be partially or completely different according to other theories.

How are diamonds evaluated?

On the matter of quality and thus the value of a cut diamond, the criteria are known as 4Cs they are Color, Clarity, Cut and Carat. Obviously, it helps to have apparatus like spectroscopes and spectrophotometers, stereomicroscopes, electric balances and also proportionscopes, but a knowledge of a basic technique enables a fairly accurate assessment of a diamond to be made with nothing more than a 10k loupe and the human eye.

Color-the point of color grading is to mark the degree of deviation from whitest possible stone down to the yellowest which is still acceptable as being of gem quality. There are a number of grading systems in use, but the most widely accepted internationally has become that of the Gemological Institute of America(GIA). Their grading certificate ma seem a bit unromantic when compared with the more descriptive and emotive terminology of some of the other systems, but they leave less room for doubt, a fact which can only be of benefit to the trade and the public.

The most commonly accepted grading systems at the moment are the two American ones-Gemology Institute of America (GIA) and American Gem Society (AGS) . Color grading judgement is not easily acquired and a beginner, for example, would detect no trace of color in the grades down to L on the GIA scale and its equivalents. This is particularly true when the diamond viewed from the front or face up position and the eye confused by the spectrum colors. Grading is therefore carried out by holding the diamond in a slim V-shaped piece of white paper or card and viewing it through the side.

More practice will enable the grader to distinguish more and more finely between stones, but to aid the process, many use grading stones of ascertained color as a basis for comparison. Lighting is vitally important. Sunlight, for example, contains ultraviolet light which can cause the diamond being examined to fluoresce very slightly blue but enough to hide any hint of yellow. This is in part why the windows of sorting rooms of the Diamond Trading Company in London all face north.

Clarity-having ascertained a diamond’s color, the next step is ti grade it according to clarity by assessing its degree of freedom from imperfections. This can be done simply by using a 10x loupe and examining the stone both internally and externally. Clarity grading is more straightforward than color grading, but arguable classifications can still arise. Once again there is no universally accepted standard despite the apparently close correspondence between the standards used in the United States, in the United Kingdom and Scandinavia.

The grades range down from “flawless” for a stone which is totally transparent and free from internal marks of any sort when seen through a 10x loupe to “heavy spotted” where the marks or inclusions are clearly visible to the naked eye. Contrary to popular opinion, very few inclusions are actually carbon spots, and many spots which appear black may nit be inclusions at all but simply other varieties of imperfection. They may be tiny bubbles or groups of bubbles, called cloud; cleavage cracks, called feathers or butterflies; which are similar to knots in wood and arise from the contact point of twinned crystals. Marks on the surface of the diamond taken to account as well as internally flaws; also included are minor imperfections resulting from cutting. But again, problem can and do arise from the fact that certain flaws are acceptable under some classifications and not under others. A number of reputable firms make up their own classifications. Tiffany‘s, for example, grades its stones into five types. If no flaws are visible through a 10x lens, the stone is graded “flawless” if a slight flaw is visible, it is graded M1 or M2 depending upon it size (M means microscopic). The third class is VS1 (very small), the fourth S (small), and the fifth and final category is “imperfect” where the flaw can be seen with naked eye. Inclusions are tiny crystals of other minerals that crystallized at the same time as the diamond. The vast majority of diamonds have such inclusions, usually crystals of olivine and garnet.

Cut-diamond cutting is a craft that requires great skill; inevitably though, some cutters will fall short of perfection and turn out misshapen stones. This is not the same as deliberately producing a stone which does not conform with the ideal proportions, since the aim may be to eliminate otherwise awkwardly positioned flaws or to balance weight against quality. In such cases the “make” of the diamond, as the cut is called, may not fit the ideal but it will not be far off; and the advantages of cutting it in this way will probably outweigh the disadvantages as a result of gains in weight and clarity. A badly cut stone is something else. It may be asymmetrical, or have badly proportioned facets of varying sizes, or culet which is not centered.

The crown may be too deep or too shallow, the girdle too thin, or the culet too pointed. With practice it is relatively easy to assess proportions by eye alone, especially by using the reflections in the table of the stone as a guide. A stone with a pavilion that is too shallow will reveal a circular reflection of the girdle when viewed through the table, giving a “fish-eye” effect. Too deep a pavilion on the other hand, will throw up a black reflection in the center of the table.

Carat-the weight of a diamond is measured in carats, an ancient measuring unit derived from the seeds of the carob tree. These small black beans are remarkably uniform in weight, but an international standard metric carat has now been agreed upon which is equal to 0.2 gram. There are 142 carats to the ounce and the carat is commonly divided into 100 points. Diamonds of less than 1 carat in weight are known as “pointers.”

A small portable chemical scale can be used to weigh diamonds to within a hundredth part of a carat, although many jewelers now use more sophisticated electric balances. It is possible to judge  weights by measurement of standard brilliant-cut stones, but it must be realized that assessments made on the basis of this sort of guide can only be approximate.

All 4Cs are taken into account in arriving at a value for a diamond, and a flawless 1.5-carat stone of good color will be worth more than a heavy spotted 2.5-carat light yellow. Nevertheless, given that a diamond is of good color, clarity and cut, carat weight is the most critical factor in determining price. One reason for this, apart from the scarcity of the bigger stones, is that while fashion and local taste may affect the desirability of color and the extreme rarity of the truly flawless diamond increases the demand for slightly less-perfect stones, weight remains the only constant and easily calculable factor under the grading systems most commonly used today.
