The Swiss Gemmological Institute SSEF has developed the Automated Spectral Diamond Inspection (ASDI) - a device which can analyse very large quantities of melee diamonds at low cost. The machine uncovers colourless synthetic diamonds, both HPHT and CVD grown, as well as colourless HPHT-treated diamonds.


SATT Gems was founded in 2014 and stands for Swiss Analytical Testing Tools. SATT Gems AG, a subsidiary of SSEF, was founded with the purpose of marketing and distributing the ASDI machine and developing new instruments for the gem and jewellery industry.
