Moonstone and Astrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Astrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Astrophyllite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 3.2-3.4 whereas that of Astrophyllite is 3.2-3.4.
