Quality testing of a gemstone by the refractive index

Quality testing of a gemstone by the refractive index

Gemstone quality testing is an important control process to verify the authenticity of a stone. The refractive index or the refraction of light is the most important signature of a gemstone. Thus, measuring the refractive index is the first step in its correct identification. Since each gemstone has its typical refractive index due to its composition and crystalline structure, using a refractometer is a quick and precise analysis as it is a non-invasive method that does not damage the stone. This technique is often used by jewelers, gemologists, and other professionals in the gemstone industry to verify the authenticity of gemstones and determine their value.

Gemstone quality testing is an important control process to verify the authenticity of a stone. Quality control testing using a refractometer, which determines the refractive index, is a quick and elegant method for assessing and analyzing the stone and ultimately determining its value.
