Spessartine and Sapphire Physical Properties

Spessartine and Sapphire Chemical Formula

While comparing Spessartine and Sapphire 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 Spessartine and Sapphire chemical formula.

• Chemical formula of Spessartine- Mn 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Sapphire- Al ₂ O ₃

Spessartine and Sapphire Specific Gravity

Another important criteria for qualitative analysis of gemstones is Spessartine and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spessartine and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Spessartine is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
