Thulite and Gibbsite Chemical Formula

While comparing Thulite and Gibbsite 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 Gibbsite chemical formula.

Thulite and Gibbsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Thulite and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 2.35 whereas that of Gibbsite is 2.35.
