Gemstone Identification with Raman Spectroscopy: Preserving Purity, Authenticity, and Trust in the Industry

Raman Spectroscopy is based on the inelastic scattering of light, commonly referred to as the Raman Effect. When monochromatic light from a laser interacts with a material, a small portion of it shifts in energy due to molecular vibrations. These shifts generate a unique spectral fingerprint that enables accurate identification of the material—be it solid, liquid, or gas.

•     Non-destructive testing
•     No sample preparation required
•     High specificity and molecular resolution
•     Analysis through transparent containers or settings

The global gemstone industry faces challenges like counterfeit stones, treatments, and imitation materials. Raman Spectroscopy has become the gold standard for objective, scientific analysis that protects the stone’s integrity and enables confident verification.

Gemstone Identification
•    Rapid, non-destructive analysis of precious/semi-precious stones and minerals
•    Differentiation of treated vs untreated stones
•    Authentication of natural and synthetic stones
 Jewellery Analysis
•    Examination of studded jewellery without removing stones
•    Through-glass analysis without unboxing or disturbing mounted stones
•    On-the-spot inspection at markets, customs, or auctions
