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

Tantalite and Sugilite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tantalite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tantalite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Tantalite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
