Discover sub-surface laser inscription technology for the diamond, gemstone and jewellery industries. We create innovative systems powered by surface and sub-surface laser technology to place high-quality and high-resolution identifiers both on and beneath the surface of gemstones. This promotes transparency, supports traceability initiatives, and offers brands a unique method of identification.
Suitable for deployment in factory, grading laboratory or standard office environments, Opsydia Systems are designed for volume operation and process over 100,000 gemstones per year. Our trio of Systems harness cutting-edge techniques developed by scientists at the University of Oxford and translate them into reliable, industrial processes for large-scale commercial endeavours.
Microscopic identifiers created by Opsydia’s Systems form a physical link between a specific diamond and its grading report, blockchain record or branded jewellery origins.
Using next-generation surface and sub-surface laser techniques, Opsydia provides methods of confirming a diamond’s identity and empowers all stages of the diamond supply chain to protect the integrity of diamonds and other gemstones.
Our secure laser technology can be used to create features inside transparent materials, including polymers, plastics and glass. The optical properties of these features can be designed to give visually stunning effects in everyday lighting conditions. Security marks, serial numbers, holograms and other aesthetic identifiers are all possible.
Opsydia is in the research and development phase for a new wave of applications in diamond-based devices. With precision control, our laser technology can create high spatial resolution electrically conductive tracks, arrays of electrodes and quantum colour centres within diamond wafers. Applications include radiation detectors, chemical sensors and quantum devices.
We work with manufacturers, industrial groups, technology specialists and commercial brands to meet their unique requirements
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."
We are excited to announce the closing of a pre-Series A funding round, led by Foresight Group and Parkwalk Advisors, with support from the University of Oxford Innovation Fund and Oxford University. This investment will accelerate the launch of our new photonics...
