GRS Aims For the Highest Pinnacle in Gemmological Research

Founded in 1996 by Dr. Adolf Peretti, GRS research has focused principally on the identification and characterization of high-quality gemstones from newly discovered mines, as well as determination of origin for gems derived from classic mining regions. The next area of research focuses on the identification of gemstone imitations, synthetics and new gem treatments. Our final area of expertise specializes in color grading and gemstone color branding, such as the well-known GRS-type Pigeon’s Blood and GRS-type Royal Blue.

Everyday, new methods are being developed for producing high-quality gem imitations for ruby, sapphire, diamond and emerald as well as many other species. In addition to these new synthetic methods, thermal and radiation treatments created to improve a stones’ appearance, plus the discovery and characterization of synthetic and treated stones have become increasingly vital. Our ongoing efforts are the best insurance for maintaining high standards found in our internationally recognized laboratory reports, which document authenticity and origin of fine gems. Our commitment to these high standards is evidenced by our investment of much of our resources back into research.
