Scolecite and Cryolite Chemical Formula

While comparing Scolecite 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 Scolecite and Cryolite chemical formula.

Scolecite and Cryolite Specific Gravity

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