GIA Demonstrates Prototype Mounted Gem Testing Device
The GIA have announced their intention to introduce for sale later this year an easy-to-operate, sophisticated desktop instrument to reliably identify natural diamonds, separating them from all simulants and from diamonds that may be synthetic or treated. The GIA mounted gem testing device combines advanced spectroscopic technology; GIA’s extensive research into the qualities of natural, treated and synthetic diamonds; and decades of diamond analysis experience to identify more than 97% of untreated natural mounted and un-mounted D-to-Z diamonds 0.9 mm or greater in diameter (approximately 0.005 carat). Diamonds that may be synthetic or treated and all simulants are referred
