Thulite and Schorl Chemical Formula
While comparing Thulite and Schorl 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 Thulite and Schorl chemical formula.
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Schorl- Na(Fe2+3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Thulite and Schorl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Thulite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
