SSEF Releases Upgraded ASDI Diamond Detector

(IDEX Online News) – The Swiss Gemmological Institute SSEF has announced the release for international export of an upgraded version of its Automated Spectral Diamond Inspection (ASDI) device. The new version comes with an automated symmetry and proportion grading function.

ASDI identifies colorless natural diamonds, by sorting out both HPHT and CVD colorless synthetic diamonds, as well any colorless HPHT-treated diamonds that may be included in a parcel.

The device can examine large numbers of colorless melee, as small as 1 millimeter in diameter or 0.4 points in size. The machine sorts at average speed of 4,000 stones per hour.

The ASDI will be on show at the DDES Diamond Detection Expo and Symposium in Mumbai, from December 14 to 16.

"The challenge that the entire diamond industry faces from undisclosed synthetic diamonds requires an industrial solution, and that is what we have developed," said Jean-Pierre Chalain, director of the Diamond Department at SSEF and Head of ASDI Development at SATT Gems, which markets the device who will be a speaker and panelist at DDES.
