Gemstone refractometers are part of the basic equipment of a gemmological and gemstone laboratory. They measure the refractive index, which provides information about the important characteristics of a gemstone. Gemstone refractometers offer an easy-to-use method for checking the authenticity and quality of a stone. Our professional devices are equipped with LEDs (589 nm), have a housing made of aluminum cast and are supplied with a polarization filter and manual.
