Feldspar and Fayalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Feldspar and Fayalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Feldspar and Fayalite Optical Properties during the identification of gemstone. Specific gravity of Feldspar is 4.392 whereas that of Fayalite is 4.392.
