Cryolite and Rutile Chemical Formula

While comparing Cryolite and Rutile 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 Cryolite and Rutile chemical formula.

Cryolite and Rutile Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Rutile Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Rutile Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 4.20-4.30 whereas that of Rutile is 4.20-4.30.
