Swiss Gemmological Institute SSEF has developed a device for automated spectral authentication of diamonds (ASDI), which allows to analyze small amounts of diamonds at a low cost.
The creation of such a device is of particular importance, taking into account the concerns of the subjects of the world diamond industry regarding the spread of the occurrence of synthetic diamonds on the market for natural (unannounced diamonds) mixed with natural stones.
The patented ASDI device analyzes round diamonds from 1.0 to 3.8 mm in diameter. The device accurately determines colorless natural diamonds and is capable of sorting up to 4 thousand stones per hour. The device identifies both colorless synthetic diamonds grown using high-pressure high-temperature (HPHT) processing technology, and those obtained by chemical vapor deposition (CVD), as well as colorless diamonds that have been processed by the HPHT method.
"The threat of undeclared synthetic diamonds, which are mixed with lots of natural mele-diamonds, is a very serious problem," said Jean-Pierre Chalain, director of the SSEF diamond division. - As part of the SSEF mission to protect the jewelery and watch industry, the ASDI device is a safe, reliable and very effective industrial solution for diamond trade participants. This device can verify the authenticity of diamonds-mele at the best price. "
