JA National Convention Will Host Diamond Detection Lab
The lab will feature technology and equipment from De Beers, GIA, and others.
This diamond detection equipment from De Beers will be on display, along with other equipment from various manufacturers, at the JA National Convention this summer.
New York—Jewelers of America’s inaugural national convention, happening next week, will allow attendees to see the latest in diamond detection technology.
Over the course of the two-day convention, the “Diamond Detection Lab” will show advancements in detection technology and test equipment from De Beers Group Industry Services, the Gemological Institute of America, Taidiam Technology, Yehuda Diamond Company, and more.
It is sponsored by De Beers.
In a press release, JA President & CEO David Bonaparte explained, “We are carefully crafting our education and content to address the needs of our members. Diamond detection is incredibly important and this lab will ensure attendees have the knowledge about detection and access to the right technology.
“De Beers Group Industry Services’ mission to grown and strengthen confidence across the diamond industry is closely aligned with JA’s mission and they are a natural partner for the Diamond Detection Lab.”
De Beers Group Industry Services President Jonathan Kendall added, “Customers, suppliers, financiers and end consumers all increasingly demand assurance when it comes to diamonds. With a range of instruments and services that provide confidence in product integrity, product knowledge and product assessment, we bring the benefit of more than 125 years of De Beers experience to help our customers with the most important C of all: Confidence.
“We look forward to being part of the Jewelers of America National Convention and helping JA’s members obtain the confidence to pass along to their customers.”
The JA National Convention will take place Sunday, July 28 and Monday, July 29 at the InterContinental New York Barclay in New York City. The lab will be open from 10:15 a.m. to noon and 1:30-5 p.m. both days.
