Vesuvianite, bi-color crystal, Canada
A beautiful crystal of bicolor Vesuvianite, green with a purple core, from the Jeffrey Mine, Asbestos, Quebec, Canada.
Vesuvianite (Idocrase) is calcium magnesium silicate, with a formula of Ca10Mg2(SiO4)5(Si2O7)2(OH)4. The name is from Mt. Vesuvius, Italy. The alternate name, Idocrase, is from the Greek eidos “form”, and krasis “mixture”, because Vesuvianite often appears to combine the crystal forms of other minerals.
Measures 1.5 x 1 x 0.7 centimeters.
