Schorl and Uvite Chemical Formula

While comparing Schorl and Uvite 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 Schorl and Uvite chemical formula.

Schorl and Uvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Schorl and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Schorl Vs Uvite during the identification of gemstone. Specific gravity of Schorl is whereas that of Uvite is .
