Achroite and Jet Physical Properties

Achroite and Jet Chemical Formula

While comparing Achroite and Jet 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 Achroite and Jet chemical formula.

• 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.
• Chemical formula of Jet- C

Achroite and Jet Specific Gravity

Another important criteria for qualitative analysis of gemstones is Achroite and Jet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite and Jet Optical Properties during the identification of gemstone. Specific gravity of Achroite is 1.19-1.35 whereas that of Jet is 1.19-1.35.
