Druzy and Topaz Chemical Formula
While comparing Druzy and Topaz 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 Druzy and Topaz chemical formula.
- Chemical formula of Druzy- Au
- Chemical formula of Topaz- Al2SiO4(F,OH)2
Druzy and Topaz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Druzy and Topaz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Druzy and Topaz Optical Properties during the identification of gemstone. Specific gravity of Druzy is 3.49-3.57 whereas that of Topaz is 3.49-3.57.
