Cavansite and Melanite Chemical Formula

While comparing Cavansite and Melanite 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 Cavansite and Melanite chemical formula.

  • Chemical formula of Cavansite- Ca(VO)Si4O10•4(H2O)
  • Chemical formula of Melanite- Ca 3Fe 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Cavansite and Melanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cavansite and Melanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Melanite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.70-4.10 whereas that of Melanite is 3.70-4.10.
