Refractive Index Testing: Emeralds have a specific refractive index – a measure of how they bend light. By using a refractometer, experts can determine if the gemstone’s refractive index matches that of genuine emeralds. Use this test on translucent and transparent stones. You can determine whether the stone is only singly refractive (SR) or doubly refractive (DR) to help identify it. Some stones can also be classified as aggregate (AGG).
