How to Measure an OTL Gemstone Refractive Index Gem Society

A gemstone with a refractive index (RI) reading that exceeds 1.81 is said to be “over the limit” (OTL). Low-cost refractometers can’t detect the highest or lowest RI values found in gemstones. While you could use a more expensive electronic refractometer for this, you have another option, especially for singly refractive gems: a micrometric scale and your microscope.get price
