Moroxite and Calcite Chemical Formula

While comparing Moroxite 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 Moroxite and Calcite chemical formula.

Moroxite and Calcite Specific Gravity

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