While comparing Scolecite 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 Scolecite and Uvite chemical formula.
Another important criteria for qualitative analysis of gemstones is Scolecite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
