Almandine and Plasma Physical Properties

Almandine and Plasma Chemical Formula

While comparing Almandine 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 Almandine and Plasma chemical formula.

• Chemical formula of Almandine- Fe 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Plasma- Cu9(AsO4)2(OH)10

Almandine and Plasma Specific Gravity

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