The Birmingham Assay Office will join forces with De Beers Group Industry Services (formerly known as IIDGR) at this year’s International Jewelley London.

The institutions, both of which have a long history of supporting the industry, aim to help enhance the industry’s confidence in synthetic diamond screening processes.

They will be showcasing live demonstrations of the award winning SYNTHdetec screening device on Sunday 1 and Monday September 2 at the Birmingham Assay Office’s stand.


De Beers Group Industry Services will also participate in a seminar on Monday September 2, 11:30-12:15, in the Knowledge Hub with David Brough and Jonathan Kendall, the group’s president.

Undisclosed synthetic diamonds threaten to not only undermine trust in the diamond pipeline, they also threaten the integrity of the wider jewellery industry, the institutions claim.

They argue that definitive identification and certification of stones from expert gemmologists using specialist testing equipment like the SYNTHdetect is important to protect pipeline integrity.

Jonathan Kendall, president of De Beers Group Industry Services, explains: “We released SYNTHdetect in 2018, and it is the first synthetic screening device to simultaneously test multiple stones in set jewellery and has the industry’s lowest referral rate (around 0.05%).

“It is designed to quickly and efficiently test the authenticity of diamonds mounted in jewellery, although the device can also be used to test loose stones of various sizes.”

Last September, the device won the 2018 Industry Innovation of the Year for Diamond Testing Technology at the JNA Awards.

Sarah North, sales director at Birmingham Assay Office adds: “Undisclosed synthetic diamonds can compromise the reputation of a business. We want to help our customers protect their business from the risks relating to undisclosed synthetic stones, and we have invested in the best technology to be able to do this.

“We are very much looking forward to joining De Beers Group Industry Services at IJL to drive this important topic and show how the jewellery industry can safeguard itself from undisclosed synthetic stones.”
