Sellaite and Triplite Chemical Formula
While comparing Sellaite and Triplite 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 Sellaite and Triplite chemical formula.

Sellaite and Triplite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sellaite and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sellaite and Triplite Optical Properties during the identification of gemstone. Specific gravity of Sellaite is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
