Tanzanite and Lazulite Chemical Formula
While comparing Tanzanite and Lazulite 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 Lazulite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references
Tanzanite and Lazulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
