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

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