Authentication of melee diamonds
SSEF authenticates batches of colourless round melee diamonds. It identifies natural diamonds and separates out lab-grown diamonds and diamond simulants.
Screening uses the ASDI and ASDI-500 instruments, both developed by SSEF. The ASDI-500 can screen diamonds as small as 0.5 mm in diameter. Stones flagged as “refer” during screening can be submitted for further analysis.

Quality control of small diamonds
The Swiss Gemmological Institute SSEF has set up a strict protocol for the quality control of colourless small diamonds (melees and baguettes), fitting with specific requirements of the watch- and jewellery industry. The detailed information available on SSEF reports help our clients to evaluate the quality of their lots of small diamonds and maintain their quality management. Our routine ensures the best reproducibility of results and provides our clients results they can trust.
We routinely control colour, clarity and cut quality of small diamonds. Each diamond that is subject to quality control is also authenticated using the ASDI instrument, with the aim of sorting out any and every synthetic diamond or diamond imitation.
