Muscovite and Achroite Physical Properties

Muscovite and Achroite Chemical Formula

While comparing Muscovite and Achroite 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 Muscovite and Achroite chemical formula.

• Chemical formula of Muscovite- KAl 2AlSi 3O 10(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
• Chemical formula of Achroite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) Formula given for elbaite.

Muscovite and Achroite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Muscovite and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Muscovite and Achroite Optical Properties during the identification of gemstone. Specific gravity of Muscovite is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
