New York--In light of industry concerns over the possible mixing of lab-grown diamonds with natural stones, the International Gemological Institute is offering free screenings of up to 100 diamonds to all members of the Diamond Manufacturers and Importers Association of America and the Diamond Dealers Club.

The screenings will be offered only for a limited time and will take place at the IGI’s New York lab, located in The French Building at 551 Fifth Ave. The lab uses advanced equipment, including De Beers’ DiamondSure and DiamondView machines, to detect lab-grown diamonds.

IGI said reason for offering the free service is two-fold: it benefits the industry as a whole to ensure that there is no mixing occurring, and it allows the lab to collect crucial, reliable data that can help determine how much mixing of synthetic and natural diamonds is going on exactly.

Established in 1975, IGI has offices and laboratories all over the world, including in New York, Antwerp, Mumbai, Tel Aviv and Shanghai. The lab has received ISO accreditation in many countries.
