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