Iddingsite and Pyrope Physical Properties

Iddingsite and Pyrope Chemical Formula

While comparing Iddingsite and Pyrope 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 Pyrope chemical formula.

• Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Iddingsite and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Iddingsite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
