Schorl and Tanzanite Physical Properties

Schorl and Tanzanite Chemical Formula

While comparing Schorl 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 Schorl and Tanzanite chemical formula.

• Chemical formula of Schorl- Na(Fe2+3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
• Chemical formula of Tanzanite- Ca₂Al₃(SiO₄)₃(OH)

Schorl and Tanzanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Schorl is 3.35 whereas that of Tanzanite is 3.35.
