Carnelian and Sapphire Physical Properties

Carnelian and Sapphire Chemical Formula

While comparing Carnelian 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 Carnelian and Sapphire chemical formula.

• Chemical formula of Carnelian- SiO₂
• Chemical formula of Sapphire- Al ₂ O ₃

Carnelian and Sapphire Specific Gravity

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