Opsydia introduces innovative surface ID system to complement existing sub-surface technology


Diamond security specialist Opsydia has expanded its portfolio of market-leading devices to include a Surface ID System (D4000), which is now accessible to international customers alongside the existing Sub-Surface ID System (D5000).

Opsydia has also announced the introduction of the D6000, which incorporates both surface and sub-surface capabilities into a single system. Both the D5000 and D6000 can place permanent Loupe ID and Nano ID features beneath the surface of diamonds.


Introducing the D4000 Surface ID System

The D4000 creates shallow, transparent and loupe-visible features on the surface of gemstones. Opsydia has developed a laser process that can create these ID features through clean ablation at very shallow depths of <50 nm. The D4000 achieves this at faster rates than existing technologies currently available on the market.

Opsydia CEO, Andrew Rimmer says: “Although Surface IDs do not have the security benefit of sub-surface features and can be polished away, we believe this addition to the Opsydia portfolio is a necessary step in diversifying our technology and ensuring it is fit for purpose for a range of businesses and their products. Fraudulent girdle inscriptions continue to be a concern in the trade, so as we branch into surface-led systems we are also researching and developing innovative ways to add extra layers of security to these features. We will share our results in due course.”

In comparison to existing surface marking technologies, the ultra-high precision Opsydia Surface ID System can create high resolution lines and dots at sizes up to 10x smaller and at shallower depths of <50 nm. This can be achieved without risking graphitisation – the introduction of black marks on a diamond – that must be removed by boiling in acid.

Other methods of transparent table inscriptions include Focused Ion Beam and photochemical techniques, which are typically slow or resource intensive. The Opsydia D4000 is a high-capacity, self-contained system capable of processing more than 100,000 stones per year. It has no complicated industrial requirements, can be operated in normal office and lab environments, and can be integrated into existing digital production management systems.


As with all Opsydia Systems, customers receive ongoing technical support and reassurances that their ID feature cannot be replicated by other Opsydia System users thanks to encrypted, Opsydia-managed software.

Andrew Rimmer continues: “We are pleased to present our trio of Opsydia Systems designed to suit the broadest possible range of businesses in the natural and laboratory-grown diamond industries. Our new Surface ID System has significant benefits over and above existing surface marking methods, and we look forward to sharing these with our existing and potential clients in the coming months.”

The D4000 Surface ID System, alongside the D5000 and D6000, are available now and ready to be deployed globally. Those interested in finding out more are encouraged to email: [email protected].
