Tanzanite and Diaspore Chemical Formula
While comparing Tanzanite and Diaspore 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 Diaspore chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Diaspore- AlO(OH)Walter Schumann , Gemstones of the world (2001) More from other references
Tanzanite and Diaspore Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
