Gemology (gemmology outside the United States) is the science, art and profession of identifying and evaluating gemstones. iGem Instruments provides you with quality gemological tools and instruments to make the task of gemstone analysis easier. Gemstone identification is performed using different instruments to study optical and other physical properties of the gemstone, such as refractive index (reflectivity index), specific gravity or the selective absorption of light in the gem material. Among instruments used are jewelers loupes, microscopes, dichroscopes, polariscopes, Chelsea filters and Ruby filters, refractometers and reflectivity meters.
