Anthophyllite and Kyanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anthophyllite and Kyanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Kyanite Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 3.53-3.65 whereas that of Kyanite is 3.53-3.65.
