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