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.

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

Versus

 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.

 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%.

 round1.02 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.
