Howlite and Zektzerite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Zektzerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Zektzerite Optical Properties during the identification of gemstone. Specific gravity of Howlite is 2.79 whereas that of Zektzerite is 2.79.
