Spinel and Thulite Chemical Formula

While comparing Spinel and Thulite 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 Thulite chemical formula.

  • Chemical formula of Spinel- MgAl2O4
  • Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)

Spinel and Thulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Spinel and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Thulite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 3.1 whereas that of Thulite is 3.1.
