Rhodolite and Spinel Physical Properties

Rhodolite and Spinel Chemical Formula

While comparing Rhodolite and Spinel 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 Spinel chemical formula.

• Chemical formula of Rhodolite- (Mg,Fe)₃Al₂Si₃O₁₂
• Chemical formula of Spinel- MgAl₂O₄

Rhodolite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodolite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
