Open letter regarding over grading certification

The diamond industry is facing a serious challenge to its integrity which could lead to major consumer confidence problems, if diamonds are sold with overstated certification. I want to stress that this is an industry problem that must be resolved by the industry in order to retain consumer confidence in our product and sustain and develop the international diamond trade.

Recently, awareness was raised regarding problems existing within a specific laboratory group and the overstating of grading from certain laboratories in this group, which has led to the exclusion of said laboratories certificates by the Rapaport Group.
