Colored Gemstone Testers, Refractive Index Meter II (PRIM II)

Product Description

Desktop digital tester that uses refractive index to quickly separate gemstones, diamonds, moissanites and other diamond simulants.

Unlike a traditional refractometer that has a limited range of R.I measurements and thus cannot be easily used to measure R.I of certain gemstones, the PRIM II is able to measure a wider range of R.I value from 1.000 to ~3.000, therefore covering the commonly known gemstones in the market and can also measure RI of diamonds, moissanites and other diamond simulants such as high zircon, strontium titanite, etc.

• Pinhole-sized light reflectivity measure on wide oval platform
• Cover cup with blackout interior to ensure light reflectivity measure is accurate
• 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
• In-built 8-piece gemstone holder
• 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
• Gemstone Dictionary in software with 57 gemstones’ properties (R.I, Color, Hardness, S.G. Value), country of origin and related information
• USB port for alternative power source and connectivity
