In the recent past, there has been increase in production of gem quality synthetic stones. There has also been rise in cases of instances faced by buyers finding that the diamonds they had purchased as believing to be Natural Diamonds were actually discovered later to be Synthetic Diamonds. In light of the seriousness of such allegations, the GJEPC saw it as a critical responsibility to study the issue of undisclosed mixing in more detail and then outline any actions that may be required to address it. With this in mind, the Natural Diamond Monitoring Committee (NDMC) was formed at GJEPC. NDMC consists of representatives from the GJEPC, BDB, GJF, GIA and other Trade Bodies in the Gems & Jewellery sector.

In 2015, NDMC had undertaken a studyto effectively address the issue of undisclosed mixing.

One of the key recommendations of the study was improving detection technology for the industry. The main objective is Driving Segregation Technology Innovation and Adoption.

  • Drive innovation by ensuring coordination among research bodies
  • Coordinate with device manufacturers to increase scale of production
  • Drive towards lower acquisition costs by enabling scale and ensuring wide participation of players

Hence, it is imperative for the gem & jewellery industry to keep abreast about the knowledge & information on synthetic diamonds, its detection through various technologies available, based on which objective, GJEPC in association with Bharat Diamond Bourse (BDB) had organized Diamond Detection Expo & Symposium (DDES 2015) in Mumbai

After the successful editions of DDES, GJEPC is organizing 3rd edition of Diamond Detection Expo & Symposium (DDES 2018) from 23rd – 25th April 2018 at Bharat Diamond Bourse (BDB), Mumbai.


The Gem & Jewellery Export Promotion Council (GJEPC) represents India, which is the fastest growing gem & jewellery market in the world and one of India's leading foreign exchange earning sectors over the years. Over the past decades, the GJEPC has emerged as one of the most active EPCs, and has continuously strived to both expand its reach and depth in its promotional activities as well as widen and increase services to its members. The industry has witnessed a considerable growth in the volume of exports.
