Ulexite and Calcite Chemical Formula
While comparing Ulexite and Calcite 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 Ulexite and Calcite chemical formula.

Ulexite and Calcite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ulexite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ulexite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Ulexite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
