Hyalite and Tanzanite Chemical Formula
While comparing Hyalite and Tanzanite 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 Hyalite and Tanzanite chemical formula.
- Chemical formula of Hyalite- SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001)
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
Hyalite and Tanzanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hyalite and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 3.35 whereas that of Tanzanite is 3.35.
