Howlite and Kainite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Kainite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Kainite Optical Properties during the identification of gemstone. Specific gravity of Howlite is 2.15 whereas that of Kainite is 2.15.
