Rutile and Natrolite Specific Gravity

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