Spinel and Agate Physical Properties

Spinel and Agate Chemical Formula

While comparing Spinel 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 Spinel and Agate chemical formula.

• Chemical formula of Spinel- MgAl₂O₄
• Chemical formula of Agate- SiO₂

Spinel and Agate Specific Gravity

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