Rhodolite and Herderite Chemical Formula
While comparing Rhodolite and Herderite 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 Herderite chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
- Chemical formula of Herderite- CaBePO 4(F,OH)Ulrich Henn and Claudio C.
Rhodolite and Herderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Herderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Herderite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 2.90-3.02 whereas that of Herderite is 2.90-3.02.
