Vesuvianite

Collectors' Tips

Vesuvianite can be identified visually. It is typically yellow, green, purple or brown, and is characterized by elongated crystals, like the one illustrated on the Amazing Story! page. The four sides of the crystals are generally of equal size. It typically has a glassy lustre.

Canada has many exceptional Vesuvianite occurrences. Quebec has some of the nicest deposits, because of the particular geologic processes which formed parts of the province.

These processes left many sections of ophiolites, which are chunks of the ocean floor that were thrust up on "dry" land when continents collided, and Vesuvianite deposits are often associated with ophiolites. Many of these ophiolite sections can be found in the Eastern Townships near towns like Thetford, Asbestos, and Mégantic.

Excellent crystals of Vesuvianite can also be found in the many old skarn deposits of the Gatineau Hills near Ottawa, and in the igneous rocks of Mont Saint-Hilaire.

Museums use heavy equipment, like this hydraulic rock trimmer being used by Assistant Collection Manager Michel Picard, to cut minerals.
