Laser technology allows safely inscribe almost anything on a diamond or colored gemstone, from personal messages to brand names, grading report numbers, bar codes and even photographs. In addition to personalizing a gemstone, micro-laser inscription facilitates identification for security and tracking purposes.
In most cases, the inscription is marked on the girdle, so as not to affect overall appearance and clarity of a diamond. However, it’s also possible to mark any other diamond or gemstone facet on specific request.
For inscription, GSI uses the state-of-the-art technologies. Every year, hundreds of thousands of diamonds and gemstones are inscribed by GSI globally.
Laser inscriptions can be as small as 10 microns. For comparison purposes, the thickness of a human hair is 75-100 microns. The thickness of a diamond girdle, which is the edge that forms its perimeter, is equivalent to a human hair.
