Adamite and Austinite Physical Properties

Adamite and Austinite Chemical Formula

While comparing Adamite 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 Adamite and Austinite chemical formula.

• Chemical formula of Adamite- Zn 2(AsO 4)(OH)Michael O’Donoghue , Gems, Sixth edition (2006)
• Chemical formula of Austinite- CaZn(AsO4)(OH)

Adamite and Austinite Specific Gravity

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