Laser Inscription on diamonds & gemstones
It has become essential for high-quality diamonds to be graded to ensure their accuracy.
The Gemological Institute of America (GIA) is widely accepted as the most accurate and popular organization that can perform this function and provide a certification.

This certification guarantees and provides confidence that it was accurately graded by an expert. This information comes in very handy in building confidence when the retailer is trying to make a sale.
In addition to analysis and grading, GIA can micro-laser inscribe a permanent, unique number on the girdle of the diamond for identification purposes.
This laser inscription is invisible to the naked eye as well as the basic jewelers 10x loupe. Once the diamond is inscribed, GIA provides a Diamond Dossiers® to accompany the stone. This is the complete analysis and description and matches the laser inscription number that was placed on the stone. This information is stored on the GIA website and is readily available to obtain a digital confirmation of the grading report.
It is important to note that even fraudsters have created fake certification papers and inscriptions to trick the industry. So, it is important to confirm the information with GIA and make sure that it is authentic, and that the certificate matches the correct stone.

How to read a laser-inscribed stone?
It is possible to read the inscription on the stone using a 20x or 30x high-powered loupe. First, you must locate the inscription on the girdle and then carefully position it so that it can be read. However, it is not very easy and almost impossible for the customer to see this.

So, what’s the best solution?
Using a digital microscope makes it quick and easy and once positioned anyone can see the inscription on the wide screen.
The Gemax Pro-II is an affordable digital microscope that is perfect for reading laser-inscribed stones.
In addition, the Gemax Pro-II is designed for taking pictures so this information can be used to print or e-mail to a customer.
