NEW YORK–(BUSINESS WIRE)–The Rapaport Group is pleased to announce the launch of a new diamond grading report – the Rapaport Investment Diamond Report (IDR). The new report conservatively grades diamonds based on Gemological Institute of America (GIA) standards. Additional gemological information including tint, location and color of inclusions as well as high resolution images are provided online and with the report.

All Rapaport Investment Diamond Reports are double tested, as they include an additional independent GIA diamond grading report. The IDR will only be issued for the best quality Round 0.50 ct. and larger, D-H, IF-VS2, excellent cut, polish and symmetry, Rapaport Specification A1 diamonds that, in the opinion of Rapaport gemologists, meet investment quality standards. Diamonds that lack overall brilliance, have features that limit trade liquidity or have borderline grades may not be issued IDRs.

“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. It will enhance the ability to trade diamonds electronically and enable new highly liquid and efficient investment diamond markets,” said Martin Rapaport, Chairman of the Rapaport Group.

Additional information about the Rapaport Investment Diamond Report as well as a sample report and Rapaport Specification A1 details are available at www.RapLab.com.
