Chrysoprase and Schorl Chemical Formula
While comparing Chrysoprase 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 Chrysoprase and Schorl chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Schorl- Na(Fe2+3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Chrysoprase and Schorl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Schorl Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
