Danburite and Plasma Chemical Formula

While comparing Danburite 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 Danburite and Plasma chemical formula.

  • Chemical formula of Plasma- Cu9(AsO4)2(OH)10

Danburite and Plasma Specific Gravity

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