Scolecite and Chiastolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Scolecite and Chiastolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Chiastolite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 3.00-3.15 whereas that of Chiastolite is 3.00-3.15.
