Opsydia launches customisable ID features for diamond trade

Opsydia, a diamond security specialist, has unveiled new classifications for its sub-surface identifiers, allowing diamond manufacturers, brands and grading houses to choose from a range of visibilities to suit their specific requirements. Using the laser technology within the Opsydia System, users can choose from Nano ID features or Loupe ID features to create a permanent physical link between a specific stone and its grading report, blockchain record or branded jewellery origins. According to the group, Nano ID features do not affect the clarity grade of diamonds, even for flawless stones, and are not detectable with a standard grading microscope. They can be placed up to 0.18 millimetres (180 microns) beneath the surface of a stone and must be read at >100x magnification or with an Opsydia ID viewer. The assertion that Nano ID features have no impact on the clarity grade of internally flawless diamonds has been independently verified and confirmed by two leading grading houses, including the Swiss Gemmological Institute, Opsydia said. Dr. Michael S. Krzemnicki, director of the Swiss Gemmological Institute SSEF, Basel, said: "We are honoured to have been able to collaborate with Opsydia in refining the criteria for a Nano ID so that it can be integrated into diamond grading practices. “Diamond traceability and security are important issues in the diamond supply chain, and it is important that such scientific techniques be developed for the trade and to ultimately strengthen consumer confidence.” IIn addition, the Loupe ID is said to be larger and denser and can be used in strategic places, such as the centre of the table, to allow valuers, grading houses and consumers to quickly distinguish laboratory-grown or branded items from natural diamonds. This group of identifiers is so named because of their visibility using a standard 10x loupe and can be placed at depths of up to 0.25 millimetres (250 microns) beneath the surface of a diamond. Neither Loupe ID or Nano ID identifiers affect the surface polish of a diamond, which means that security features can be placed beneath the surface without compromising its finish and/or value. The Opsydia System uses a high-precision, ultrafast laser to place logos, alphanumeric sequences or coded shapes (known as identifiers) beneath the surface of a diamond. The laser is tightly focused only once it passes the surface of a diamond, therefore only creating the identifier at a selected depth without affecting the surface condition or polish. It can be applied beneath the surface of a diamond in a range of locations, such as the table or a specific facet.
