About Us

International Institute of Diamond, IID, was set up to bridge the trust gap in the gemstone industry. IID does this by inculcating ethical values and transparency through education and awareness programs, standardization and certification procedures.

IID has highly skilled and experienced professionals to appraise the value and quality of the precious stones using the state of the art technology and machineries. The certification sets a new benchmark and gives more confidence to the customer. IID certificates narrate the true story behind the purity, and rarity of a diamond. IID certification helps customers to identify natural diamonds from their synthetic counterparts.

At IID, a diamond goes through stringent quality checking based on the parameters related to the 4Cs – cut, color, clarity and carat. The quality checking procedures enable IID to bring out detailed reports on how precious a stone really is.

A gemstone may be similar in appearance to a famous and high valued rare stone. But at IID, the tests, the machineries and the highly experienced and skilled professionals prove its real worth. IID rely on the most modern technology and uses microscope with 50x magnifying lenses, machines including Raman’s spectroscopy, synthetic diamond detectors and CVD diamond tester detect synthetics, treatments and other enhancement processes.

Thus, IID empowers the customer with confidence to flaunt their certified gems with the true knowledge of its real value. Because, they should shine as much on the outside, as they really do on the inside.
