A gem refractometer is an excellent tool for identifying gemstones, but can be expensive and difficult to use untrained. If you are able to use one, check whether the gemstone has a refractive index from 1.565 to 1.602, the range for natural emeralds. Refractive index is measured using a refractometer and is a key characteristic . A gem refractometer is an excellent tool for identifying gemstones, but can be expensive and difficult to use untrained.

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.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 .

Use these gemology cheat sheets to review color and clarity grading, as well as special information on diamond and opal. You can also review basic gem identification testing procedures for the refractometer, polariscope, and specific gravity.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.

Refractive Index Testing: Emeralds have a specific refractive index – a measure of how they bend light. By using a refractometer, experts can determine if the gemstone’s refractive index matches that of genuine emeralds. Use this test on translucent and transparent stones. You can determine whether the stone is only singly refractive (SR) or doubly refractive (DR) to help identify it. Some stones can also be classified as aggregate (AGG).
