Jet lignite and Rubellite Chemical Formula
While comparing Jet lignite and Rubellite 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 Jet lignite and Rubellite chemical formula.

Jet lignite and Rubellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jet lignite and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jet lignite and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Jet lignite is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
