Opsydia, a spin-out company of the University of Oxford, is able to create laser mark on the sub-surface of a melee diamond.
A diamond in 0.5mm can now have an alphanumeric sequence, coded shape or logo placed at depths of 0.18mm or more beneath the surface of a diamond to create a physical link to a supply chain record or branded jewellery origin.
Opsydia CEO, Andrew Rimmer, said: “With this technology, the natural diamond trade has more opportunities to secure the identity of its products and use sub-surface features to create ‘fail safes’ within its supply chain. Similarly, luxury jewellery brands wishing to fight back against counterfeiting may wish to include an identifier in a specific pavé diamond and assure their customers that only pieces with this nano-scale identity feature are legitimate.”
