Diopside and Ulexite Chemical Formula
While comparing Diopside and Ulexite 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 Diopside and Ulexite chemical formula.
- Chemical formula of Diopside- CaMgSi2O6
- Chemical formula of Ulexite- NaCaB 5O 6(OH) 6 · 5H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Diopside and Ulexite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Ulexite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Ulexite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 1.65-1.99 whereas that of Ulexite is 1.65-1.99.
