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

Rutile and Sphene Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Sphene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Sphene Optical Properties during the identification of gemstone. Specific gravity of Rutile is Not Available whereas that of Sphene is Not Available.
