Shigaite and Calcite Physical Properties

Shigaite and Calcite Chemical Formula

While comparing Shigaite 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 Shigaite and Calcite chemical formula.

• Chemical formula of Calcite- CaCO 3Ulrich Henn and Claudio C.

Shigaite and Calcite Specific Gravity

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