Thulite and Jacobsite Chemical Formula
While comparing Thulite and Jacobsite 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 Thulite and Jacobsite chemical formula.
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)
Thulite and Jacobsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
