Sunstone and Tantalite Chemical Formula
While comparing Sunstone and Tantalite 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 Sunstone and Tantalite chemical formula.

Sunstone and Tantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Tantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Tantalite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 5.2 whereas that of Tantalite is 5.2.
