Andradite and Agate Physical Properties

Andradite and Agate Chemical Formula

While comparing Andradite and Agate 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 Andradite and Agate chemical formula.

• Chemical formula of Andradite- Ca 3Fe 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Agate- SiO₂

Andradite and Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Andradite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Agate Optical Properties during the identification of gemstone. Specific gravity of Andradite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
