Gedrite and Rhodochrosite Chemical Formula
While comparing Gedrite and Rhodochrosite 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 Gedrite and Rhodochrosite chemical formula.
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)

Gedrite and Rhodochrosite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gedrite and Rhodochrosite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Rhodochrosite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 3.0-3.3 whereas that of Rhodochrosite is 3.0-3.3.
