Opsydia, a University of Oxford spinout, has unveiled ground-breaking new technology that will help address the risk of tampering and counterfeiting in the diamond sector.
Using high precision lasers, Opsydia can make tiny marks, less than 1/50th of the size of a human hair, below the surface of diamonds. Unlike current industry standard security marking on the diamond surface, these marks sit within the stone so cannot be polished off economically. Also, they can be so small that they have no effect on the grading or quality of the gems.
