Diamond
Opsydia's secure laser marking technology is set to transform diamond security. Current industry-standard diamond identification is achieved by surface marking on the girdle of diamonds, the results of which are easy to polish off or replicate on inferior stones. View the video below to see how Opsydia technology can create tiny marks beneath the surface of diamonds, substantially improving their security without sacrificing clarity or grade.
The marks are customisable in shape, size and location; the laser process parameters can be tuned to create marks visible through a jeweller’s loupe, or to be much smaller and only visible through a higher magnification microscope, such that clarity grading is unaffected.
Surface untouched

On the left you can see the mark in focus, below the surface.
On the right, the camera is focused on the surface and you can see the surface is untouched.
Custom precision
High-magnification image of a diamond marked beneath the surface.
Line width is less than 1/50th of the width of a human hair, making the mark invisible to the naked eye.
The shape, size, location and visibility can all be customised.
Logos, serial numbers, grading data or specific cryptographic marks are all possible.
Securely verified

Opsydia precision marks are designed to preserve clarity and grading, while being detectable with suitable viewing technology.
Advanced viewers will decode and read encrypted information written in diamonds, interfacing securely with diamond databases and blockchain solutions.
