Forsterite and Cryolite Chemical Formula

While comparing Forsterite 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 Forsterite and Cryolite chemical formula.

Forsterite and Cryolite Specific Gravity

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