Rhodolite and Dravite Chemical Formula
While comparing Rhodolite and Dravite 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 Rhodolite and Dravite chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
- Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
Rhodolite and Dravite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Dravite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
