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.
