Jet and Starlite Chemical Formula
While comparing Jet and Starlite 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 and Starlite chemical formula.

Jet and Starlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jet and Starlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jet and Starlite Optical Properties during the identification of gemstone. Specific gravity of Jet is 3.91-4.73 whereas that of Starlite is 3.91-4.73.
