Tanzanite and Liddicoatite Chemical Formula
While comparing Tanzanite and Liddicoatite 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 Liddicoatite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Liddicoatite- Ca(Li 2Al)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Tanzanite and Liddicoatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Liddicoatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Liddicoatite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 3.02 whereas that of Liddicoatite is 3.02.
