Fantastic jewel of gem Garnet var. Grossular with green phantoms from the famous Jeffrey mine, Quebec, Canada. The Grossular crystals are gem and clear up to 6mm. They have rich green cores due to Chromium. The crystals are sharp rhombic dodecahedrons with glassy luster. The green cored Garnets are among the most unusual and rare Jeffrey mine Garnets. This was mined long time ago. Fine specimen from this closed mine. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some side contacts. On acrylic base.
Gorgeous gem-green Garnets!
