SSEF and UNIMEC introduce the ASDI-500, world’s most precise automated small synthetic diamond screener The ASDI-500 Automated Diamond Spectral Inspection system, jointly developed by SSEF and UNIMEC, which will be unveiled at GemGenève International Gem and Jewellery Show, November 3-6, 2022. The ASDI-500 is able to detect and extract synthetics and simulants as small as half a millimetre in diameter, at the astounding speed of 700 stones per hour. BASEL, SWITZERLAND – OCTOBER 24, 2022: The Swiss Gemmological Institute SSEF and UNIMEC SA, a robotics company also headquartered in Switzerland, have announced the release of the ASDI-500, a new version of the Automated Diamond Spectral Inspection device. Able to screen very large quantities of round colourless polished melee, detecting and extracting synthetics and simulants from among t

natural diamonds, the ASDI-500 is the only such system operating today that has the degree of precision to handle stones as small as 500 microns (0.5 mm) in diameter. When it was introduced eight years ago, the ASDI was the very first device able to automatically screen large batches of colourless diamonds. It was developed to protect the integrity of the Swiss watch and jewellery industry, which as major consumers of melee must be able to ensure that undisclosed synthetics and simulants are not being sold as natural diamonds. Prior to the release of the ASDI-500, no automatised authentication...
