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

Starlite and Faustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Starlite and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Starlite and Faustite Optical Properties during the identification of gemstone. Specific gravity of Starlite is 2.9 whereas that of Faustite is 2.9.
