Howlite and Vesuvianite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Vesuvianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Vesuvianite Optical Properties during the identification of gemstone. Specific gravity of Howlite is 3.32-3.43 whereas that of Vesuvianite is 3.32-3.43.
