Gematrat

print
Gematrat was developed in 1997 as a way to permanently treat emeralds, leaving them in a stable and permanent state once finished. The process has been defined as 'gemstone branding' and begins with a very extensive cleaning of the stone which may take weeks or even months in some cases. The stone's tiny fissures and cracks are then filled with the colorless Gematrat substance, which is said not to leak or discolor. The substance also contains a tracer which glows blue under ultraviolet light.

According to the producers of the treatment, you can put Gematrat treated gems in an ultrasonic cleaner, a steamer, and even recut the stone without damage. The stones are marketed with an American Gemological Laboratories? (AGL) report.
