Actinolite and Spinel Chemical Formula

While comparing Actinolite and Spinel 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 Actinolite and Spinel chemical formula.

  • Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
  • Chemical formula of Spinel- MgAl2O4

Actinolite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Actinolite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Actinolite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Actinolite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
