Iddingsite and Sard Chemical Formula

While comparing Iddingsite and Sard 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 Iddingsite and Sard chemical formula.

  • Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
  • Chemical formula of Sard- SiO 2Ulrich Henn and Claudio C.

Iddingsite and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Iddingsite and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Sard Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 2.58-2.63 whereas that of Sard is 2.58-2.63.
