Moonstone and Hollandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Hollandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Hollandite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 5.05 whereas that of Hollandite is 5.05.
