Anthophyllite and Actinolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anthophyllite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 3.00 whereas that of Actinolite is 3.00.
