For Fast Launch
Principal diamond security specialist, Opsydia, has unveiled new classifications for its sub-surface identifiers, allowing diamond producers, producers and grading houses to pick out from a wide range of visibilities to go properly with their explicit requirements.
Utilising the laser know-how contained in the Opsydia System, prospects can choose from Nano ID choices or Loupe ID choices to create a eternal bodily hyperlink between a selected stone and its grading report, blockchain report or branded jewellery origins.
This alphanumeric identifier is decrease than 50 μm all through and is not seen at 40x magnification.
Nano ID choices do not affect the readability grade of diamonds, even for flawless stones, and are normally not detectable with an abnormal grading microscope. Nano ID choices will probably be positioned as a lot as 0.18 millimetres (180 microns) beneath the ground of a stone and ought to be study at >100x magnification or with an Opsydia ID viewer – a instrument in a position to finding out identifiers that is at current inside the enchancment part.
The assertion that Nano ID choices haven’t any impression on the readability grade of internally flawless diamonds has been independently verified and confirmed by two principal grading houses, along with the Swiss Gemmological Institute (SSEF).
“We’re honoured to have been ready to collaborate with Opsydia in refining the elements for a Nano ID so that it might be built-in into diamond grading practices. Diamond traceability and security are important factors inside the diamond present chain, and it is vital that such scientific strategies be developed for the commerce and to lastly strengthen shopper confidence,” says Dr. Michael S. Krzemnicki, Director of the Swiss Gemmological Institute SSEF, Basel.
In distinction, a Loupe ID is larger and denser and might be utilized in strategic areas, such as a result of the centre of the desk, to allow valuers, grading houses and prospects to quickly distinguish laboratory-grown or branded objects from pure diamonds. This group of identifiers is so named resulting from their visibility using an abnormal 10x loupe and will probably be positioned at depths of as a lot as 0.25 millimetres (250 microns) beneath the ground of a diamond.

Neither Loupe ID or Nano ID identifiers affect the ground polish of a diamond, which means safety measures will probably be positioned beneath the ground with out compromising its finish and/or price.
With this know-how, the pure diamond commerce has the freedom to include secure identifiers inside its diamond present with out compromising the weather that assure rarity and market price. By establishing the strategies to create its most invisible identifiers to date, Opsydia is introducing the pure diamond sector to a novel methodology for addressing its core challenges, akin to enhancing stone security, establishing daring traceability initiatives and defending in direction of fraud, non-disclosure and completely different counterfeiting points.
The Opsydia System makes use of a high-precision, ultrafast laser to place logos, alphanumeric sequences or coded shapes (known as identifiers) beneath the ground of a diamond. This laser is tightly focused solely as quickly because it passes the ground of a diamond, subsequently solely creating the identifier at a particular depth with out affecting the ground state of affairs or polish. It might be utilized beneath the ground of a diamond in a wide range of areas, such as a result of the desk or a selected aspect.
Clockwise from L-R: An alphanumeric identifier, a holographic attribute inside a diamond, a QR code inside a diamond. ID choices will probably be customised to any width, pattern or type to go properly with the individual.
The Opsydia System (approx. one metre huge and customary doorway accessible) is based on forefront laser know-how developed on the Faculty of Oxford. It would in all probability place distinctive identification choices in diamonds and is ready to processing 50,000 to 100,000 stones per yr in an industrial environment. Encryption strategies make certain that each Opsydia system can solely write authorised logos or identifiers stopping counterfeiting and defending mannequin integrity.
Opsydia know-how is deployable all through the globe and will probably be utilised by pure diamond and laboratory grown diamond specialists. Inside the spring, Opsydia will announce further collaborations with worldwide diamond commerce our our bodies.
