Schorl and Plasma Physical Properties

Schorl and Plasma Chemical Formula

While comparing Schorl and Plasma 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 Plasma 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 Plasma- Cu9(AsO4)2(OH)10

Schorl and Plasma Specific Gravity

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