Rutile and Hardystonite Chemical Formula
While comparing Rutile and Hardystonite 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 Rutile and Hardystonite chemical formula.

Rutile and Hardystonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Hardystonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Hardystonite Optical Properties during the identification of gemstone. Specific gravity of Rutile is 3.396-3.443 whereas that of Hardystonite is 3.396-3.443.
