Opal and Cryolite Physical Properties

Opal and Cryolite Chemical Formula

While comparing Opal 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 Opal and Cryolite chemical formula.

• Chemical formula of Opal- SiO₂ · nH₂O
• Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.

Opal and Cryolite Specific Gravity

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