Description

A green jewel of garnet var. grossular var. chromian from the famous Jeffrey mine, Quebec, Canada. The crystals are gem and clear to 3mm. They have a very deep and saturated grass-green color due to chromium. They are with a sharp rhombic dodecahedral habit, glassy luster and irresistible color. Light green diopside crystals grow on the base. A nice piece from this closed mine. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some contacts. On acrylic base.

Fascinating gem-green garnets!
