Euclase and Sugilite Chemical Formula

While comparing Euclase 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 Euclase and Sugilite chemical formula.

Euclase and Sugilite Specific Gravity

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