Moonstone and Peridot Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Peridot Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Peridot Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 1.54-1.55 whereas that of Peridot is 1.54-1.55.
