Dolomite and Sard Chemical Formula

While comparing Dolomite and Sard 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 Dolomite and Sard chemical formula.

Dolomite and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dolomite and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dolomite and Sard Optical Properties during the identification of gemstone. Specific gravity of Dolomite is 2.58-2.63 whereas that of Sard is 2.58-2.63.
