Grandidierite and Strontianite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Grandidierite and Strontianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Grandidierite and Strontianite Optical Properties during the identification of gemstone. Specific gravity of Grandidierite is 3.63-3.79 whereas that of Strontianite is 3.63-3.79.
