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