Rhodolite and Pollucite Chemical Formula
While comparing Rhodolite and Pollucite 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 Pollucite chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12

Rhodolite and Pollucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
