Mimetite and Annabergite Chemical Formula
While comparing Mimetite and Annabergite 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 Mimetite and Annabergite chemical formula.

Mimetite and Annabergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Mimetite and Annabergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mimetite and Annabergite Optical Properties during the identification of gemstone. Specific gravity of Mimetite is 3.07 whereas that of Annabergite is 3.07.
