Gem Refractometer Gemstone ldentification LED Light Diamond Detector Jewelry Testing Tools

Features:
This refractometer is designed to measure the refractive index of gemstones and solid materials.  The primary use of a refractometer is to measure the angle at which light is bent or refracted through a stone.
Lightweight and compact, it is easy to carry. It provides gemstone recognition as it differs from gemstones to gemstones. The refractometer is also one of the few instruments that can provide you with information on opaque gems and transparent gems.
The transparent gemstone is tested and the surface is polished flat, which is very suitable for separating gemstones.
 Quickly and accurately identify single and double gems. Helps identify diamonds, moissanite and colored gems, speeds up the identification of gems in the package, does not require RI liquids, and results in uniform and reliable results each time, with a clearly visible display for easy reading measurements.
