Tanzanite and Calcite Chemical Formula
While comparing Tanzanite and Calcite 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 Calcite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Calcite- CaCO 3Ulrich Henn and Claudio C.
Tanzanite and Calcite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
