Jacobsite and Tanzanite Chemical Formula
While comparing Jacobsite and Tanzanite 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 Jacobsite and Tanzanite chemical formula.
- Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
Jacobsite and Tanzanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jacobsite and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 3.35 whereas that of Tanzanite is 3.35.
