Dioptase and Mottramite Physical Properties

Dioptase and Mottramite Chemical Formula

While comparing Dioptase and Mottramite 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 Dioptase and Mottramite chemical formula.

• Chemical formula of Mottramite- PbCu(VO4)(OH)

Dioptase and Mottramite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Mottramite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Mottramite Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 5.9 whereas that of Mottramite is 5.9.
