Selenite and Celestine Physical Properties

Selenite and Celestine Chemical Formula

While comparing Selenite and Celestine 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 Selenite and Celestine chemical formula.

Selenite and Celestine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Selenite and Celestine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Selenite and Celestine Optical Properties during the identification of gemstone. Specific gravity of Selenite is 3.90-4.00 whereas that of Celestine is 3.90-4.00.
