Nifontovite and Adamite Chemical Formula
While comparing Nifontovite and Adamite 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 Nifontovite and Adamite chemical formula.

Nifontovite and Adamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nifontovite and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nifontovite and Adamite Optical Properties during the identification of gemstone. Specific gravity of Nifontovite is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
