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 . The refractometer is one of the most important tools in a gemological laboratory. It indicates (not measures) the refraction index of a gemstone, which often gives vital clues to the identity of a gemstone. Although one would expect a refractometer to measure the refraction of light inside a gemstone, this is not the case.Learn how to determine a gem’s optic character with a refractometer and how to identify optical effects you may encounter during gem identification tests.

What kind should you buy and how do you use it.
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. The jeweler's refractometer utilizes the concept of total internal reflection to reveal the RI of a gem placed into optical contact with the prism/hemicylinder. The refractometer displays the point at which total internal reflection occurs as a shadow edge against a calibrated scale.This tutorial video will demonstrate how to determine a gemstone's refractive index, optic character, and other properties with this instrument.
