Cavansite and Legrandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cavansite and Legrandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Legrandite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.98-4.04 whereas that of Legrandite is 3.98-4.04.
