Topaz and Microlite Chemical Formula

While comparing Topaz and Microlite 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 Topaz and Microlite chemical formula.

  • Chemical formula of Topaz- Al2SiO4(F,OH)2
  • Chemical formula of Microlite- (Ca,Na) 2Ta 2O 6(O,OH,F)Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

Topaz and Microlite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Topaz and Microlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Microlite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 5.5 whereas that of Microlite is 5.5.
