Marvelous specimen of bi-color Vesuvianite with Diopside from the famous Jeffrey mine, Quebec, Canada. The Vesuvianite crystals have from intense purple color to apple-green areas. They are gemmy, with strong luster and are well shaped. Colorless platy Diopsides are seen too. They are transparent and gemmy with strong luster. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some contacts. On acrylic base.
Charming!
