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

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