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

Jeremejevite and Sellaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jeremejevite and Sellaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jeremejevite and Sellaite Optical Properties during the identification of gemstone. Specific gravity of Jeremejevite is 3.14-3.16 whereas that of Sellaite is 3.14-3.16.
