Leucite and Ruby Specific Gravity

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