Hyalite and Uvite Physical Properties

Hyalite and Uvite Chemical Formula

While comparing Hyalite and Uvite 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 Hyalite and Uvite chemical formula.

• Chemical formula of Hyalite- SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001)
• Chemical formula of Uvite- Ca(Mg 3)MgAl 5(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Hyalite and Uvite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hyalite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
