Determination of the refractive index of a gemstone for its verification

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 of inspection and analysis and an important check for verifying the stone.

Gemstones: testing their composition and crystalline structure using the refractive index. This will identify the stone and avoid confusion.
