- Identify diamonds, moissanite and colored gems, speed up the identification of gems in the packaging, with a clearly visible display for easy reading. Differentiate between diamonds, moissanite and other gemstones in seconds.
- The gemstone refractometer is compact, lightweight and easy to carry, which is perfect for people and jewelers in jewelry factories.

Features
- Detects the quality (intensity) of light reflected from the surface of cut and polished gemstones. This intensity reading is fed into a micro controller where calculations and conversions are made to obtain a refractive index reading for the gemstone.
- Fast and accurate identification of single biaxial gems. Refractive index reading range is around 1.000 to 3.000.
- It can measure the refractive index of gemstones non-destructively, quickly and accurately. You can get the exact refractive index of the gemstone from the refractive index reference table included in the package.
- Accurately determine other optical properties of gemstones. This refractometer is highly accurate and easy to operate. Support continuous detection, no need to wait.
