Gemological FTIR Spectroscopy

Advanced Molecular Analysis for Gemstone Identification and Authentication

The Gemology advanced Laboratory utilizes high-precision, USA-made Fourier Transform Infrared (FT-IR) spectroscopy to provide definitive molecular characterization of gemstones. This facility is equipped with Thermo Scientific OMNIC™️ software, an advanced platform that enables non-destructive analysis, identifying gemstones and their treatments by detecting specific molecular vibrational patterns. Our laboratory serves as a critical center for distinguishing between natural, synthetic, and treated gemstones, ensuring the highest standards of integrity in the jewelry and gemstone industry.

RGS classic instruments

Polariscope

The polariscope is a key gemology tool that uses polarized light to analyze a gem’s crystal structure. At the Razi Gemological Institute, it is a vital first step for fast, non-destructive screening. It instantly distinguishes single-crystal gems from aggregates, reveals strain in synthetics, and helps detect imitations, forming a core part of Razi’s precise identification workflow.

Refractometer

A refractometer is a fundamental gemological instrument that measures a gemstone’s refractive index (RI), its unique “light fingerprint.” At the Razi Gemological Institute, it is the primary tool for conclusive gem identification. By precisely quantifying how light bends within a stone, it provides definitive data to distinguish between look-alike gems, confirm natural origins, and detect synthetics or treatments, making it indispensable for accurate and authoritative analysis.

S.G kits

Specific Gravity (S.G.) kits are essential tools for measuring a gemstone’s density, a key identifying property. At the Razi Gemological Institute, these precise hydrostatic weighing kits provide a non-destructive and highly diagnostic test. By comparing the gem’s weight in air versus in water, experts can calculate its specific gravity, a definitive value that helps distinguish between gem species with similar appearance but different densities, such as citrine and topaz, or to confirm the identity of materials like amber. This method is a cornerstone of Razi’s rigorous and conclusive identification protocol.
