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

Siderite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Siderite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Siderite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Siderite is 3.1 whereas that of Thulite is 3.1.
