Unlike a traditional refractometer, PRIM II is able to measure the range of RI value from 1.000 to ~3.000, therefore covering the commonly known gemstones in the market, including diamonds and moissanites. In addition, a fast and easy test can be done, without the inconvenience and messy usage of RI liquid.
The new software enables the user to further eliminate the list of possible colored gemstones by entering known values such as color, hardness and S.G. value. Further information regarding gemstone properties, common found locations can also be easily found.
Please note, that the digital refractive index meter operation is similar to the operation of an optical refractometer, thus the testing of mounted stones may be difficult or impossible. Mounted gemstones could only be reliably tested if no part of the metal setting is located above the stone facet being tested (normally the table).
