Nuummite and Gibbsite Chemical Formula

While comparing Nuummite 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 Nuummite and Gibbsite chemical formula.

Nuummite and Gibbsite Specific Gravity

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