06 Nov SSEF’s ASDI achieves 100% accuracy during testing by DPA’s ASSURE Program
The Automated Spectral Diamond Inspection (ASDI) device, an automated small synthetic diamond screener that was first released in 2014 by the Swiss Gemmological Institute SSEF, has been evaluated by the ASSURE Program of the Diamond Producers Association (DPA) and proved to be one the few instruments to have successfully passed 100% of the tests administered. This means that all stones categorised by the instrument as “diamonds” were indeed natural diamonds, all diamond simulants were correctly sorted out, and all synthetic diamonds were correctly referred for definitive testing.
As the final test report indicates, the ASDI passed all tests with flying colours, unfailingly screening out every synthetic diamond and diamond simulant, operating at a speed of more than 6,500 stones per hour. The detailed report is available on the DPA’s ASSURE Program website.
The ASDI system is still available and is being marketed by SATT Gems Ltd., a subsidiary of the Swiss Gemmological Institute SSEF, one of the world’s leading gemmological laboratories.
