Gem Refractometer, RHG181 1.30-1.81 Jewelry Professional High Accuracy Gemstone ldentification Portable Gemological Gemelogy Refractometer with Electric Torch, Reflective Index Fluid for Gemologists
Refractive Index is one of the most important optical parameters used to identify and authenticate polished precious and semi-precious gemstones..
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..
This 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)..
In fact, you can also use this tool to measure R.I. for many minerals in crystal form as long as the crystals have a flat and polished face..
