Grossular (Colorless)
Jeffrey Mine, Asbestos, Quebec, Canada
Thumbnail, 2.0 x 1.8 x 1.6 cm
Jeffrey Mine Garnets are the world's finest for grossular variety of the Garnet family, hands down. While the great classic ones are an orange-amber color, there are other fine Grossulars from Jeffrey in rare sporadic pockets that may have greenish or pink, or even no color. The colorless grossulars are particularly rare, and the best find I know of came out in the mid 1990s. This specimen is from the noted Melanson thumbnail collection, and was acquired in 1996 from that find. It is a HUGE single crystal in cluster. In this case, we have a cluster of gemmy colorless-vanilla crystals, the largest of which is 1.8 cm. They have good form, with finely striated faces. The crystals have glassy luster, and are gemmy to translucent. Overall this is a significant thumbnail, if a little unusual, for this amazing (now closed) mine and the species!
