Jacobsite and Moldavite Chemical Formula
While comparing Jacobsite and Moldavite 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 Jacobsite and Moldavite chemical formula.

Jacobsite and Moldavite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jacobsite and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
