Gem Refractometer
Gem refractometer
Product Description
Each gem has a typical refractive index due to its chemical composition and crystallization structure. The gem refractometer can be used to observe the optical properties and the structure of a gemstone. Through the parameters you can judge whether the gem is an anisotropic or isotropic stone. The stone needs a flat and polished facet. FULL SCALE Contact Liquid (RI Fluid) is also needed when testing.
