Rutile and Dravite Physical Properties

Rutile and Dravite Chemical Formula

While comparing Rutile and Dravite 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 Dravite chemical formula.

Rutile and Dravite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rutile and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Dravite Optical Properties during the identification of gemstone. Specific gravity of Rutile is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
