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.
