According to a press release, the Rapaport Investment Diamond Report (IDR) will conservatively grade diamonds according to Gemological Institute of America (GIA) standards. It will also provide gemmological information online, such as tint, location, and colour of inclusions, as well as high-resolution images of the stone.
“The Rapaport Investment Diamond Report is designed to identify the best diamonds in the market while providing the trade, investors, and consumers with the highest level of confidence in quality,” said Martin Rapaport, chair of the Rapaport Group. “It will enhance the ability to trade diamonds electronically and enable new highly liquid and efficient investment diamond markets.”
The stones will be tested twice and will be accompanied by an additional independent GIA diamond grading report. IDRs will only be issued for the best quality round diamonds that meet Â the following requirements:
• weigh .50 carats or more;
• are D to H colour;
• are IF to VS2;
• have excellent cut, polish, and symmetry;
• and are Rapaport Specification A1 diamonds that, in the opinion of Rapaport gemmologists, meet investment quality standards.
Diamonds lacking overall brilliance, have features that limit trade liquidity, or have borderline grades may not be issued IDRs.
