Quality testing of a gemstone using the refractive index

Quality testing of a gemstone using 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 based on its composition and crystalline structure, refractive index quality control testing is a quick and elegant method for assessing and analyzing the stone and ultimately determining its value.
