6.4" Polished Slab Of Clay Canyon Variscite - Old Collection Stock

This is a polished section of rare and very collectable variscite from the Little Green Monster Variscite Mine in Clay Canyon, Utah. The material was collected between 1937 and 1940 and almost none has been collected since. Most of it, and likely these specimens were sold out of the Smithsonian gift shop, then the National Museum.

The specimen is 6.4" wide and .35" thick, it has been cut flat and polished on both sides and includes the secondary mineral Crandallite (yellow banding) and Wardite (blue banding). It comes with an acrylic display stand.

Clay Canyon & the Little Green Monster Variscite Mine

Variscite, closely related to turquoise, is a secondary mineral formed by direct deposition from phosphate-bearing water that has reacted with aluminium-rich rocks in a near-surface environment. It occurs as fine-grained masses in nodules, cavity fillings, and crusts. Variscite often contains white veins of the calcium aluminium phosphate mineral crandallite. It is sometimes confused with turquoise, but variscite is usually greener in color.
