Securing the Identity of Diamonds

Our pioneering technology places unique identity features, known as identifiers, beneath the surface of a diamond without affecting its surface or surface polish. Identifiers can be incorporated into any size from significant down to melee, both at loupe visible and microscopic sizes, to secure a diamond’s identity, support transparency initiatives and create a physical link between a specific diamond and its grading report, blockchain record or branded jewellery origins.

Next-Level Diamond Security

Current industry-standard diamond identification is achieved by surface marking the girdle of diamonds, which can be easily polished away or fraudulently replicated. There are many examples of inferior diamonds being marked with false grading report numbers to mask their true identity.

Our permanent, microscopic identifiers are placed beneath a diamond’s surface in a way that can’t be polished away or removed without re-cutting a stone, making efforts to do so uneconomical. This is the next-generation of secure and tamper-proof identification for diamonds. 

Supporting Brand Identity

The Opsydia System is a companion to luxury fine jewellery houses who want to secure the identity of their finished pieces, protect against brand counterfeiting and alleviate consumer security concerns.

Our identifiers can take the form of unique brand logos, limited edition collectors’ numbers or dates to demonstrate the authenticity of diamonds and the finished jewellery creations they are in.

Disclosing Laboratory-Grown Diamonds

Opsydia works with both natural diamond specialists and laboratory-grown diamond businesses. Our unique identifiers support the drive towards complete and honest disclosure and aid grading laboratories, retailers and valuers in distinguishing diamond origin.

For example, the Opsydia System is utilised by Lightbox Jewelry to add a loupe-visible identifying feature to each of its laboratory-grown diamonds for complete transparency.

Our Identifiers

Opsydia Identifiers are categorised by their visibility: Nano ID or Loupe ID.

Nano ID features do not affect the clarity grade of diamonds, even for flawless stones, and are not detectable with a standard grading microscope. Nano ID features 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 Opsydia Viewer technology.

Nano ID features have been independently assessed by two leading grading houses, including the Swiss Gemmological Institute (SSEF).

A Loupe ID can be viewed with a standard 10x magnification eye loupe and have to date been used as part of brand awareness initiatives. These identifiers are larger, more visible and can be used in strategic places, such as the centre of the table, to display a brand logo or quickly distinguish laboratory-grown from natural diamonds.

This group of identifiers can be placed at depths of up to 0.25 millimetres (250 microns).

 

What Can Identifiers Look Like?

The shape, size and location of identifiers can all be customised to suit specific brand requirements or integrate with supply chain initiatives. Three common choices for identifiers are alphanumeric sequences, brand logos and/or coded shapes.

Identifiers can take the form of QR codes within diamonds or other coded features.

Your Diamonds in Safe Hands…

Opsydia’s Systems (approx. one metre wide and standard doorway accessible) can place unique identity features in all diamonds, down to melee stones of just 0.5 millimetres in diameter and is capable of processing 100,000+ stones per year in an industrial environment. Encryption techniques ensure the unique identifiers of one company with an Opsydia System cannot be fraudulently acquired and processed by another Opsydia user. This means your identifiers are always secure, accessible only to you and guarded by our in-house specialists.

Forward Thinking Enterprise

By creating a solution that is unique to the trade and easily deployed across the globe, our technology has won the support of leading miners, manufacturers and grading houses who share our commitment to authentic diamond security.

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."
