Willemite and Cryolite Chemical Formula

While comparing Willemite and Cryolite 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 Willemite and Cryolite chemical formula.

Willemite and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Willemite and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Willemite is 2.97 whereas that of Cryolite is 2.97.
