Before learning to determine optic character, be sure to review our article on using a refractometer to determine the RIs of faceted gems. 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. Presidium Gem Tester II (PGT II) - Testing Emerald, Diamond, Sapphire, Ruby, Nephrite. A tutorial on the use of the Gem Refractometer, to help to identify a transparent gemstone. This video.

For a better understanding of the refractometer, you first need to understand refraction.

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 .Fortunately a refractometer can measure the critical angle of a gem allowing light to form a shadow line on the calibrated scale of the refractometer and so you can directly read the R.I. from the scale. Most gemologists are aware that, given a well-polished flat facet, the refractometer can determine the refractive index (RI) of a gem, and also the full birefringence of a doubly refractive gem.
