Cryolite and Siderite Chemical Formula

While comparing Cryolite and Siderite 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 Siderite chemical formula.

Cryolite and Siderite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Siderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Siderite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 3.83-3.89 whereas that of Siderite is 3.83-3.89.
