Labradorite and Cinnabar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Cinnabar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Cinnabar Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2 whereas that of Cinnabar is 2.
