Rutile and Anthophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Rutile is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
