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 .This tutorial video will demonstrate how to determine a gemstone's refractive index, optic character, and other properties with this instrument. Your refractometer can provide important clues for accurate gemstone identification.Refractive Index Testing: the General Procedure. To measure the RI of a faceted gem with a refractometer: Place a bright light source behind the refractometer and direct it into the light window. Place a tiny drop of RI fluid on the hemicylinder.
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.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 .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.
