IGI also grades synthetic diamonds on a commercial scale.Diamond World, Tower C-101/104, 1st Floor, Mangadh Chowk, Varachha Road, Surat - 395 006 India Phone : + 550 Fax : + 551 For Certification : suratigi.orgThe IGI QR codes will not only easily assist sales associates in communicating relevant gemological grading information – 4Cs (cut, color, clarity and carat), authentication of precious metals, etc. – but this tool is also directly available to consumers, assuring them of an item’s quality.WP Diamonds allows you to check diamond grading reports for any diamond that has a report or certificate. Enter the details online for the laboratory in question.

After GIA, they are actually the 2nd most well-known lab in the world.
On clarity, some diamonds were graded as VVS2 by EGL and “ IF” by GIA, despite there being detectable inclusions at 10x magnification. We feel GIA’s methodology does not provide the most accurate representation of color in the diamond. In one example of color discrepancies, with three blues that are obviously different shades even to an untrained consumer, EGL graded them ‘fancy light blue’, ‘fancy blue’ and ‘fancy intense blue’ respectively, while GIA graded them all the same ‘fancy intense blue’. In early 2010, we sent the same batch of blue diamonds to both labs. GIA grades fancy color based on the single darkest point in the diamond, most likely because mined colored diamonds are exponentially more expensive, the more color they have. We have found the opposite to be true for synthetic diamonds, though are unsure as to the underlying reasons why.Two of the more important factors when considering a diamond are color and clarity.
Please note that GIA typically takes four to six weeks to grade a synthetic diamond. The subjective properties have sometimes been identical, but when they are not, we have found GIA typically grades color darker and clarity more clean than EGL and IGI.If you wish to have a diamond graded by GIA, or another major lab, we can do so for $200 per diamond. On the printed report, GIA does not list the specific clarity 1 or 2, just the written name (“Very Slightly Included” instead of VS1 or VS2).For the diamonds we have sent to multiple labs, the objective measures come back essentially identical.
