Colorful Vesuvianite var. Manganoan crystal. It has an intense purple color and colorless tip. Vesuvianite has very strong luster - sparking and shiny. It is gemmy and well formed. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. In very good condition – some small nicks and base contact. On acrylic base.
Lovely!
