Your refractometer can provide important clues for accurate gemstone identification.A gem refractometer is the best tool for refractive index testing. Learn how to use this instrument to conduct this and other gem identification tests.The refractometer is an essential instrument for gemmologists looking to identify gemstones. It can be a tricky tool to master, but if you learn the correct .A refractometer measures the angle at which light rays refract “bend” as they move through a gemstone, and provide a reading (Refractive Index or R.I.) from a scale seen though the eyepiece of the refractometer. Because R.I. is unique for each type of .

Learn how to determine a gem’s optic character with a refractometer and identify optical effects you may encounter during gem identification tests. Before learning to determine optic character, be sure to review our article on using a refractometer to determine the RIs of faceted gems. Although one would expect a refractometer to measure the refraction of light inside a gemstone, this is not the case. Instead it is based on a unique optical phenomenon named Total Internal Reflection (or TIR). For a better understanding of the refractometer, you first need to understand refraction. Contents. 1 Basic. Using a Gem Refractometer from http://www.1001raregemstones.com. The index of refraction is calculated from Snell's law and can be calculated from the compos.
