- 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.
- Features : PRIM II Software An enhancement to enable users to further eliminate the list of possible colored gemstones by entering known values such as color.
- hardness and S.G. value, Powered up by USB... For more details please check product description.
