1.30 ~ 1.81 RI Range Gemological Refractometer + Index oil Flashlight Polarizing Lens CL-181

Refractive  Index is one of the most important optical parameters  used to identify and authenticate polished precious  and semi-precious gemstones. This Gemological refractometer  is a low cost, lightweight measuring instrument used  by jewelers and traders of gemstones   to measure polished stones over a refractive index  range of 1.30 to 1.81 RI. The instrument can also  be used to identify whether a particular stone is Isotropic  or Anistropic (uniaxial or biaxial).

Gemological  (Gemstone) Refractometer is your primary and most powerful  tool in gemstone identification. As with a typical critical  angle refractometer, it will measure the Refractive  Index of faceted stones.
