Spinel and Prasiolite Chemical Formula
While comparing Spinel and Prasiolite 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 Prasiolite chemical formula.
- Chemical formula of Spinel- MgAl2O4
- Chemical formula of Prasiolite- SiO 2Ulrich Henn and Claudio C.
Spinel and Prasiolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 2.65 whereas that of Prasiolite is 2.65.
