Howlite and Sanidine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Sanidine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Sanidine Optical Properties during the identification of gemstone. Specific gravity of Howlite is 2.54-2.61 whereas that of Sanidine is 2.54-2.61.
