A cool specimen of gem garnet var. grossular crystals with green phantoms from the famous Jeffrey mine, Quebec, Canada. The grossular crystals have vivid green cores, which are result of chromium, surrounded by transparent colorless areas. The crystals to 2mm have a sharp crystallization, a glassy luster and an irresistible contrast. Apple-green diopside covers the base. Green cored garnets are among the most unusual and rare Jeffrey mine Garnets. This was mined decades ago - the mine is closed now. It displays on both sides. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some contacts. On acrylic base.

Marvelous!
