Quartz and Sugilite Chemical Formula
While comparing Quartz 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 Quartz and Sugilite chemical formula.

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