A splendid specimen of rare colorless garnet var. grossular crystals to 1mm with diopside from the famous Jeffrey mine, Quebec, Canada. The colorless garnets are among the rarest in the world. The grossular crystals are gem, completely transparent and clear like water. They have a rhombic dodecahedral sharp crystallization and glassy luster. A marvelous spray of diopside needles grow above. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. In very good condition – some small contacts.

Fascinating!
