Vesuvianite, was found first in the Italian Volcano of Mt. Vesuvius. Its earlier synonym Idocrase is not used any more. Some of these stones are brilliantly colored, but many of the mineral samples are normally dull. The stones that were mined in Quebec at the Jeffery Quarry in Asbestos are seen to be classic forms, truly stunning.
(Repeating unit) Ca10 (Mg, Fe) 2Al4 (SiO4) 5 (Si2O7) 2 (OH, F) 4
Derivation of Name
Abraham Gottlob Werner renamed this mineral as "vesuvian" in the year 1795. Originally, Moritz Anton Cappeler in 1723 had named it "Hyacinthus Dictus Octodecahedricus. Jean-Baptiste Louis Romé de L’Isle renamed it in 1772 as "Hyacinte du Vesuve." Rene Just Haüy changed it to "Idocrase", until it was changed again to “Vesuvianite"
Vesuvianite is available in nature in the form of tetragonal crystals in limestones and skarn deposits which have been administered by contact metamorphism. Initially it got discovered contained in blocks or next to lavas on Mount Vesuvius, giving it its name.
It is a very energetic stone that brings the will in line with the heart, creating a totality and veracity that is fairly good for an individual. It encourages interest for life and brings the audacity to change.
Its main sources are found in Asbestos, Quebec, Canada; New England and California in the USA; Ural Mountains, Russia, Mt Vesuvius, Italy; plus Switzerland.
Vesuvianite, also named as Idocrase, is a captivating mineral, initially found on the volcano, Mt Vesuvius, giving it one of its names. Idocrase, its other name, is derived from the Greek meaning “mixed" form, referring to its crystals presenting a combination of additional mineral forms. The crystals fall in the tetragonal symmetry class and demonstrate a square cross-section vertical to the long axis. Tetragonal crystals are rare. Thankfully, Vesuvianite crystals are nicely shaped.
Comes in green, brown Yellow; colorless, white, violet, bluish green, blue, red, pink, black, usually zoned.
