This great NEW gemological refractometer can be used for measuring refractive index of GEM. It is characterized by small volume and less weight; easy to carry. And it is a popular instrument used in the jewelry market.

Refractive index is one of most important of optical parameters. Gloss of gem can be estimated by the parameter. The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its inherent refractive index. The index of double refraction can be also measured. Through this parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative. It has a polarizing filter and the eyepiece removable.
