Fibrolite and Jacobsite Chemical Formula
While comparing Fibrolite 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 Fibrolite and Jacobsite chemical formula.

Fibrolite and Jacobsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fibrolite and Jacobsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fibrolite and Jacobsite Optical Properties during the identification of gemstone. Specific gravity of Fibrolite is 4.76-5.03 whereas that of Jacobsite is 4.76-5.03.
