Linarite and Diaspore Chemical Formula

While comparing Linarite and Diaspore 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 Linarite and Diaspore chemical formula.

Linarite and Diaspore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Linarite and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Linarite and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Linarite is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
