Topaz and Muscovite Chemical Formula
While comparing Topaz and Muscovite 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 Muscovite chemical formula.
- Chemical formula of Topaz- Al2SiO4(F,OH)2
- Chemical formula of Muscovite- KAl 2AlSi 3O 10(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
Topaz and Muscovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
