Analcime and Crocoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Analcime and Crocoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Analcime and Crocoite Optical Properties during the identification of gemstone. Specific gravity of Analcime is 5.90-6.10 whereas that of Crocoite is 5.90-6.10.
