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.
