Malachite and Schorl Chemical Formula
While comparing Malachite 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 Malachite and Schorl chemical formula.
- Chemical formula of Malachite- Cu2CO3(OH)2
- Chemical formula of Schorl- Na(Fe2+3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Malachite and Schorl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Malachite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Malachite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Malachite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
