Designed to identify polished gemstones, the PRM measures the quantity of light reflected through the gemstone in order to provide an instant reading of its reflective index. Includes a built in reflectivity chart which list the most common gemstones for immediate reference. The Presidium Reflectivity Meter is developed to help you distinguish between Diamond from its simulants. Reflectivity Measurement makes use of the fact that diamond and its simulants reflect light proportionally to their respective refractive index, harness and perfection of polish. Since the first reflectivity instrument for gemstones identification was built by L.C. Trumper in 1959, this concept has been widely used in the jewelry trade. Today, there are many newly released Diamond simulants with its thermal properties that are so close to those of Diamond. Operates thru a 120v power adapter or 9 volt battery. Alkaline batteries should be used. Ordinary batteries may be used but will give a shorter working life. Detailed instructions included.$
