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

Rutile and Prase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Prase Optical Properties during the identification of gemstone. Specific gravity of Rutile is 2.64-2.69 whereas that of Prase is 2.64-2.69.
