Tanzanite and Seraphinite Chemical Formula
While comparing Tanzanite and Seraphinite 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 Tanzanite and Seraphinite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)
Tanzanite and Seraphinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
