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.
