The Gem & Jewelery Export Promotion Council of India, GJEPC, has taken action in connection with the industry's challenge of blending synthetic diamonds with natural diamonds. This concern arose after media reports, and after several cases of actual mixing, identified by Dalumi Diamond India Pvt Ltd and Narola Gems. GJEPC and the Indian Diamond Exchange (BDB) drew attention to these issues and initiated investigations, and demanded explanations from companies. Based on the results of these studies, the legal group GJEPC and the Indian Diamond Exchange (Bharat Diamond Bourse, BDB) will begin the litigation in accordance with the statute of both organizations.
In August 2013, GJEPC formed the National Diamond Monitoring Committee (NDMC), along with various trade associations such as BDB, the Gem & Jewelery Federation (GJF) and the Mumbai Diamond Traders Association (Mumbai Diamond Merchants Association, MDMA). This step was taken to deal with "synthetic" diamonds and develop a strategy to protect the common interests of the natural diamonds industry; to strengthen consumer confidence by encouraging the proper disclosure and preservation of the trust factor in the industry; to ensure the proper separation of natural diamonds and synthetic diamonds;
