SSEF introduces the Automated Spectral Diamond Inspection

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 development of the instrument is all the more important following concerns expressed by members of the global diamond industry in the past year after undisclosed lab-grown diamonds were mixed in with parcels of natural diamonds.
