Starlite and Siderite Chemical Formula
While comparing Starlite 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 Starlite and Siderite chemical formula.

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