Zektzerite and Howlite Chemical Formula
While comparing Zektzerite and Howlite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Zektzerite and Howlite chemical formula.

Zektzerite and Howlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zektzerite and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zektzerite and Howlite Optical Properties during the identification of gemstone. Specific gravity of Zektzerite is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
