Rhodochrosite and Verdelite Chemical Formula
While comparing Rhodochrosite and Verdelite 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 Rhodochrosite and Verdelite chemical formula.
- Chemical formula of Rhodochrosite- MnCO3
- Chemical formula of Verdelite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) Formula given for elbaite.
Rhodochrosite and Verdelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Verdelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Verdelite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 2.90-3.40 whereas that of Verdelite is 2.90-3.40.
