Serandite and Austinite Physical Properties

Serandite and Austinite Chemical Formula

While comparing Serandite and Austinite 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 Serandite and Austinite chemical formula.

• Chemical formula of Serandite- Na(Mn2+ ,Ca) 2Si 3O 8(OH)Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Austinite- CaZn(AsO4)(OH)

Serandite and Austinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Serandite and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Serandite and Austinite Optical Properties during the identification of gemstone. Specific gravity of Serandite is 4.12 whereas that of Austinite is 4.12.
