The Gemological Institute of America (GIA) has launched a device that can detect synthetic diamonds – even those already mounted in jewellery.
Until now, the majority of detectors could only determine the authenticity of loose stones.
The device created by the GIA will use advanced spectroscopic technology, which can pinpoint natural, untreated diamonds above approximately 0.005 carats with D to Z color.
If it finds a diamond may be lab-grown, treated or a simulant, it refers the stone for further examination.
The device will be sold in late 2017, at a price the GIA said is “accessible to the trade.”
Research is being done to extend the device’s ability to screen pink diamonds and other materials.
Susan Jacques, CEO of GIA, said: “There is perhaps no greater issue in the gem and jewellery trade today than concerns about the possibility of undisclosed synthetic diamonds being inadvertently sold to consumers.
“This new instrument is the culmination of more than 60 years of GIA research into synthetic diamonds and will give the trade — including retail jewelers — the ability to have immediate confidence in their diamonds.”
The device is made to work with GIA’s current screening equipment, including DiamondCheck and its Melee Analysis Service.
