Aegirine and Verdelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aegirine and Verdelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aegirine and Verdelite Optical Properties during the identification of gemstone. Specific gravity of Aegirine is 2.90-3.40 whereas that of Verdelite is 2.90-3.40.
