Uvite and Diaspore Chemical Formula

While comparing Uvite 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 Uvite and Diaspore chemical formula.

Uvite and Diaspore Specific Gravity

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