Idocrase and Epidote Physical Properties

Idocrase and Epidote Chemical Formula

While comparing Idocrase and Epidote 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 Idocrase and Epidote chemical formula.

• Chemical formula of Idocrase- Ca10(Mg,Fe)2(Si2O7)2(SiO4)2O(OH)2
• Chemical formula of Epidote- CaAl 2(Fe3+ ,Al)Si 3O 12(OH)Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

Idocrase and Epidote Specific Gravity

Another important criteria for qualitative analysis of gemstones is Idocrase and Epidote Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Idocrase and Epidote Optical Properties during the identification of gemstone. Specific gravity of Idocrase is 3.25-3.50 whereas that of Epidote is 3.25-3.50.
