Nice bi-color Vesuvianite decorated by Diopside. Vesuvianites have varying color from purple to pleasing apple yellow-green. With very strong luster - sparking, shiny and gemmy crystals. Diopside translucent and almost colorless. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. In very good condition – some side contacts. On acrylic base.
Pleasing!
