Citrine and Star Sapphire Chemical Formula
While comparing Citrine and Star 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 Citrine and Star Sapphire chemical formula.
- Chemical formula of Citrine- SiO2
- Chemical formula of Star Sapphire- Al 2O 3Ulrich Henn and Claudio C.
Citrine and Star Sapphire Specific Gravity
Another important criteria for qualitative analysis of gemstones is Citrine and Star Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Citrine and Star Sapphire Optical Properties during the identification of gemstone. Specific gravity of Citrine is 3.90-4.05 whereas that of Star Sapphire is 3.90-4.05.
