Prehnite and Wavellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Wavellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Wavellite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 2.36 whereas that of Wavellite is 2.36.
