Scolecite and Dumortierite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Scolecite and Dumortierite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Dumortierite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 3.26-3.41 whereas that of Dumortierite is 3.26-3.41.
