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.

  • Chemical formula of Quartz- SiO2
  • Chemical formula of Sugilite- KNa 2(Fe3+ ,Mn3+ ,Al) 2Li 3Si 12O 30Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

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.
