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 system is designed to support the diamond industry against the threat of small synthetic diamonds mixed into parcels of natural colourless melée diamonds.

ASDI is able to conclusively identify colourless natural diamonds, by sorting out both HPHT and CVD colourless synthetic diamonds, as well any colourless HPHT-treated diamonds that may be included in a parcel. It is the only automated system that can examine large numbers of stones of colourless melee, as small as 1 millimetre in diameter or 0.4 points in size, at high speed and at low cost.
