London Gem forum welcomed global line-up of speakers and guests.

The Gemmological Association of Great Britain (Gem-A) hosted its 21st annual conference earlier this month, welcome a host of international speakers and delegates.

The event was praised by attendees who described it as informative and welcoming. The four-day event focused on news and developments from the gem and jewellery trade over the past year, with guest speakers from the US and the Netherlands.


Topics covered included colour grading systems, Brazilian and Colombian emeralds, and West African gems. The use of lab equipment and methods of distinguishing natural and synthetic high pressure high temperature (HPHT) and chemical vapour deposition (CVD) diamonds were also covered.

Avril Plant of Plant’s in Staffordshire attended the conference. She said: “This was the first Gem-A Conference I’ve attended and I’m determined that it will not be my last. There were so many enticing activities spread over four days.”

“The conference has been an amazing experience. We enjoyed eight lectures from thrilling speakers from all over the world, all specialists in their subjects. Historians, gem dealers, prospectors and gemmology laboratory scientists — such a feast,” Plant added.

Ron Ringsrud, author of Emeralds: A Passionate Guide, dubbed the forum a “first-class display”.
