Selenite and Antigorite Physical Properties

Selenite and Antigorite Chemical Formula

While comparing Selenite and Antigorite 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 Antigorite chemical formula.

• Chemical formula of Selenite- CaSO4·2H2O
• Chemical formula of Antigorite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Selenite and Antigorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Selenite and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Selenite and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Selenite is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
