Anthophyllite and Adamite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anthophyllite and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Adamite Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
