While comparing Anyolite and Heliotrope 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 Anyolite and Heliotrope chemical formula.
Another important criteria for qualitative analysis of gemstones is Anyolite and Heliotrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anyolite and Heliotrope Optical Properties during the identification of gemstone. Specific gravity of Anyolite is 2.61 whereas that of Heliotrope is 2.61.
