Clinochlore and Prehnite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Clinochlore and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinochlore and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Clinochlore is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
