Labradorite and Muscovite Chemical Formula
While comparing Labradorite 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 Labradorite and Muscovite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Muscovite- KAl 2AlSi 3O 10(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
Labradorite and Muscovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Muscovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Muscovite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.78-2.88 whereas that of Muscovite is 2.78-2.88.
