The refractive index of gemstones is a very important optical parameter. The gloss of the gemstone can be determined by this parameter. Since different gemstones have a fixed refractive index, all kinds of gemstones can be determined according to the refractive index.

In addition, birefringence can also be measured.

This parameter can be used to determine whether a gemstone is uniaxial or biaxial.

This gem refractometer is small in size and light in weight.

Easy to carry and popular in the jewelry industry.
