The president of the International Diamond Manufacturers Association (IDMA), Maxim Shkadov, said in a popular appeal that his organization is extremely concerned after the publication by Rapaport of an article about overstated characteristics of diamonds.
In an article entitled "Honest Grading", published last month and sent to over 77,000 diamond industry participants, Martin Rapaport writes that over 100 thousand stones were valued at a total cost of $ 1 billion. The main source of overvalued diamonds is the international gemological laboratory EGL, using the terminology of the Gemological Institute of America (GIA), but applying other standards that lead to overstating the characteristics of diamonds.
IDMA's appeal says: "You can not lose confidence of customers when buying diamonds. Playing with certificates is not allowed in the market. Laboratories must independently certify diamonds to confirm the characteristics for the buyer. "
"Any falsification must have a thorough investigation right up to criminal prosecution of dishonest" figures "for certification. The diamond should not turn into an object of unscrupulous speculation, "Maxim Shkadov emphasized in his address. "If such facts are discovered, we suggest that we immediately contact the police to organize a thorough investigation."
