Phosphosiderite and Calcite Chemical Formula
While comparing Phosphosiderite and Calcite 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 Phosphosiderite and Calcite chemical formula.

Phosphosiderite and Calcite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phosphosiderite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phosphosiderite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Phosphosiderite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
