Nice specimen of Garnet var. Andradite var. Demantoid from the famous Jeffrey mine, Quebec, Canada. Usually these Demantoids sit on white Asbestos base but this one is different. The crystals are up to 4mm with rhombic dodecahedral habit. They are gemmy. The color is rich green. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some small nicks and contacts. On acrylic base.
Cute!
