Topaz and Bowenite Chemical Formula
While comparing Topaz and Bowenite 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 Topaz and Bowenite chemical formula.
- Chemical formula of Topaz- Al2SiO4(F,OH)2
- Chemical formula of Bowenite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
Topaz and Bowenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Bowenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Bowenite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.58-2.80 whereas that of Bowenite is 2.58-2.80.
