Willemite and Labradorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Willemite and Labradorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite and Labradorite Optical Properties during the identification of gemstone. Specific gravity of Willemite is 2.69-2.72 whereas that of Labradorite is 2.69-2.72.
