Grandidierite and Fluorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Grandidierite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Grandidierite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Grandidierite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
