Diopside and Anthophyllite Specific Gravity

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