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

Rutile and Emerald Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Emerald Optical Properties during the identification of gemstone. Specific gravity of Rutile is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
