Fibrolite and Sugilite Physical Properties

Fibrolite and Sugilite Chemical Formula

While comparing Fibrolite and Sugilite 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 Sugilite chemical formula.

Fibrolite and Sugilite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fibrolite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fibrolite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Fibrolite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
