Sulfur and Natrolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sulfur and Natrolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sulfur and Natrolite Optical Properties during the identification of gemstone. Specific gravity of Sulfur is 2.20-2.26 whereas that of Natrolite is 2.20-2.26.
