It’s located on 47th Street in New York’s Diamond District.
Gemological Science International just opened a second New York City location that will be dedicated solely to screening set jewelry for man-made diamonds. Seen here is a GSI grader using the DiamondView, a machine created by De Beers’ IIDGR for detecting CVD-grown diamonds.
New York—Gemological Science International just opened a new facility in New York that does nothing but test jewelry for lab-grown diamonds.
The lab caters to GSI’s retail customers in the United States, and the company said it will serve as a hub for both manufacturers and retailers that want to have their diamond jewelry screened before it goes into a store.
It is located at 37 W. 47th St., between Fifth and Sixth Avenues, and will be the second New York location for the company, which has a lab at 581 Fifth Ave. as well.
GSI said it plans to continue to expand worldwide, starting with Hong Kong, where it opened a new facility this month.
GSI Hong Kong is located at Kaiser Estate Phase 1, 37-45 Man Yue St, Hunghom KL Hong Kong, Ste. A3 (5th floor). The lab grades loose diamonds and diamond jewelry, and screens and tests jewelry for lab-grown diamonds.
For more information on Gemological Science International or any of its labs, visit GSI’s website, email info@gemscience.net or call 212-207-4140.
