- Chemical formula of Verdite- NaFeS2•2(H2O)
Lepidolite and Verdite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lepidolite and Verdite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lepidolite and Verdite Optical Properties during the identification of gemstone. Specific gravity of Lepidolite is 2.80-3.0 whereas that of Verdite is 2.80-3.0.
