Sapphire and Fire Agate Physical Properties

Sapphire and Fire Agate Chemical Formula

While comparing Sapphire and Fire 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 Sapphire and Fire Agate chemical formula.

• Chemical formula of Sapphire- Al ₂ O ₃
• Chemical formula of Fire Agate- SiO 2Arthur Thomas , Gemstones (2009)

Sapphire and Fire Agate Specific Gravity

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