This Desktop Digital Tester efficiently seperates diamonds, moissanites and other colored gemstones by identifying their respective Refractive indexes.
It has wider range of R.I. measurements than any other traditional refractometer - 1.000 to ~3.000. Diamond simulants such as high zircon, strontium titanite, etc. can also be tested
Features :
- Simple and easy to use
- Instantly displays direct R.I reading on digital index LED display panel
- In-built Refractive Chart for referencing diamonds and simulants above R.I reading of 1.8
- Pocket-sized Refractive Index Chart pull-out with R.I readings for 55 stones
- PRIM II complementary software to help users find out the possible colored gemstone using data on various gemstone properties
- USB port for alternative power source and connectivity
- No waiting time between tests
- Runs on batteries or with recommended Presidium AC adaptor
- Pinhole-sized light reflectivity measure on wide oval platform
- Cover cup with blackout interior to ensure light reflectivity measure is accurate
- Gemstone Dictionary in software with 57 gemstones’ properties (R.I, Color, Hardness, S.G. Value), country of origin and related information
- No need for messy R.I liquids
- Continual elimination of possible gemstones via software program through input of known values such as R.I, color, hardness and S.G.
- Light and compact tester
