Rhodolite and Gedrite Chemical Formula
While comparing Rhodolite and Gedrite 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 Gedrite chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Rhodolite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
