Heliotrope and Boracite Chemical Formula
While comparing Heliotrope and Boracite 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 Heliotrope and Boracite chemical formula.

Heliotrope and Boracite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Heliotrope and Boracite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Heliotrope and Boracite Optical Properties during the identification of gemstone. Specific gravity of Heliotrope is 2.95-2.96 whereas that of Boracite is 2.95-2.96.
