1.6" Vesuvianite Crystal Cluster - Jeffrey Mine, Canada
This is a lustrous, 1.6" wide cluster of vesuvianite crystals from the famous Jeffrey Mine in Quebec, Canada. Now that this mine is closed, these specimens are getting hard to come by. This specimen was collected by Tony Gordian.
Vesuvianite, also known as idocrase, is a green, brown, yellow, or blue silicate mineral. Vesuvianite occurs as tetragonal crystals in skarn deposits and limestones that have been subjected to contact metamorphism. It was first discovered within included blocks or adjacent to lavas on Mount Vesuvius, hence its name. Attractive-looking crystals are sometimes cut as gemstones.
