Carnelian and Rossmanite Chemical Formula
While comparing Carnelian and Rossmanite 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 Carnelian and Rossmanite chemical formula.
- Chemical formula of Carnelian- SiO2
- Chemical formula of Rossmanite- ◻(LiAl 2)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Carnelian and Rossmanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Carnelian and Rossmanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Carnelian and Rossmanite Optical Properties during the identification of gemstone. Specific gravity of Carnelian is 3 whereas that of Rossmanite is 3.
