Lepidolite and Ruby Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lepidolite and Ruby Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lepidolite and Ruby Optical Properties during the identification of gemstone. Specific gravity of Lepidolite is 3.97-4.05 whereas that of Ruby is 3.97-4.05.
