Gemological Instruments

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  its refractive index (reflectivity index), specific gravity (relative density) or the selective absorption of light in the gem material. Among the instruments of gemology are Jeweler's Loupes, Microscopes, Dichroscopes, Polariscopes, Chelsea Filters and Ruby Filters, and Refractometers and Reflectivity Meters.
