Digital Gemological Gemstone Gem Refractometer with buit in light

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.
