Automated Spectral Diamond Inspection
- Colourless round melee diamond authentication
- Separating diamond imitations
- Separating HPHT treated diamonds
- Separating synthetics (CVD & HPHT)
- Customizable size-sorting (optional)
ASDI stands for Automated Spectral Diamond Inspection. It is a device which can analyse and authenticate very large quantities of colourless melee diamonds at a low cost.
The machine uncovers colourless synthetic diamonds, both HPHT and CVD grown, as well as colourless HPHT-treated diamonds.
In 2007, the Swiss Gemmological Institute SSEF and the electronic laboratory of the University of Basel joined their expertise and launched the ASDI project. After five years of research & development, OPTEC Industries brought their know-how in automation and size-sorting.
Finally in 2013, the first ASDI machine was operational at the Swiss Gemmological Institute SSEF and since then, has screened more than a million of colourless melees hereby protecting the Swiss watch and jewellery industry.
As a result, four ASDI units are now operating at two major Swiss diamantaires and two major Swiss watch and jewellery groups.
