Adamite and Plasma Chemical Formula

While comparing Adamite 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 Adamite and Plasma chemical formula.

  • Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael O’Donoghue , Gems, Sixth edition (2006)
  • Chemical formula of Plasma- Cu9(AsO4)2(OH)10

Adamite and Plasma Specific Gravity

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