Zoisite and Hexagonite Chemical Formula
While comparing Zoisite and Hexagonite 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 Zoisite and Hexagonite chemical formula.
- Chemical formula of Zoisite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Hexagonite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Zoisite and Hexagonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zoisite and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
