Labradorite and Meionite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Meionite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Meionite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.78 whereas that of Meionite is 2.78.
