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.
