Prasiolite and Iddingsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prasiolite and Iddingsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prasiolite and Iddingsite Optical Properties during the identification of gemstone. Specific gravity of Prasiolite is 2.5-2.8 whereas that of Iddingsite is 2.5-2.8.
