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

Sugilite and Mellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sugilite and Mellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Mellite Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 1.58-1.60 whereas that of Mellite is 1.58-1.60.
