Scolecite and Forsterite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Scolecite and Forsterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Forsterite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 3.23-3.26 whereas that of Forsterite is 3.23-3.26.
