Apophyllite and Simpsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is Not Available whereas that of Simpsonite is Not Available.
