Topaz and Dolomite Chemical Formula
While comparing Topaz and Dolomite 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 Topaz and Dolomite chemical formula.

Topaz and Dolomite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Dolomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Dolomite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.80-2.95 whereas that of Dolomite is 2.80-2.95.
