Fayalite and Caledonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
