Specifications

Refractive Index is one of the most important optical parameters used to identify and authenticate polished precious and semi-precious gemstones. The GI-181-2 Gemological refractometer is a low cost, lightweight measuring instrument used by jewellers 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. It comes with Refractometer Index oil, Mini Flashlight, Storage Box, Polarizing Lens and Leather Carrying Case! Plus an option to get an extra bottle of 1.800 Refractive Index Oil just by adding a small amount to your order, see Available Options.
