Splendid combo of bi-color Vesuvianite and Diopside. Vesuvianites have from intense purple color  to apple-green areas. The crystals are gem with a strong luster and are well shaped. Some Diopsides grow above. They are transparent and gemmy. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. In good condition – some contacts.

Marvelous!
