Erythrite and Albite Chemical Formula
While comparing Erythrite and Albite 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 Erythrite and Albite chemical formula.

Erythrite and Albite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Erythrite and Albite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Erythrite and Albite Optical Properties during the identification of gemstone. Specific gravity of Erythrite is 2.60-2.65 whereas that of Albite is 2.60-2.65.
