Iddingsite and Sugilite Chemical Formula
While comparing Iddingsite and Sugilite 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 Sugilite chemical formula.
- Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)
- Chemical formula of Sugilite- KNa 2(Fe3+ ,Mn3+ ,Al) 2Li 3Si 12O 30Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Iddingsite and Sugilite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Iddingsite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iddingsite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Iddingsite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
