Montebrasite and Chrysoprase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Montebrasite and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
