Rhodolite and Crystal Opal Chemical Formula
While comparing Rhodolite and Crystal Opal 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 Crystal Opal chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
- Chemical formula of Crystal Opal- SiO 2 + H 2OUlrich Henn and Claudio C.
Rhodolite and Crystal Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Crystal Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Crystal Opal Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 1.97-2.22 whereas that of Crystal Opal is 1.97-2.22.
