This is a showy miniature from the historic Monte Cristo zinc mine in northern Arkansas, of a highly unusual style for smithsonite! The piece consists of numerous, 2 to 4 mm, vibrant and saturated yellow botryoids of Greenockite-included Smithsonite that are liberally scattered on drusy Quartz crystals which are barely discernible due to their coating of bright yellow Greenockite. The Smithsonites have a satin luster and are largely opaque due to the abundance of Greenockite internally. The presence of drusy Quartz is almost totally hidden by an early generation dusting of Greenockite over them! Close inspection reveals a minor amount of sub-mm crystals of Greenockite at the interstices of the Smithsonite botryoids in places. This is a really cool, beautiful and rare piece of a combination and locality we rarely see. From the collection of Henry de Linde (March 21, 1923 – April 4, 2019) of Hot Springs, Arkansas. Henry was one of the most prominent figures in the history of Arkansas mining and mineral collecting. Along with being a miner, mineral collector and an amateur mineralogist, de Linde was one of the founders of the Coon Creek Association mineral club. He was the owner of several key localities in Arkansas including the Diamond Jo Quarry (on the south rim of Magnet Cove), the type locality for Delindeite, which was named in his honor in 1987. On the back of a larger specimen of the same identical style in the collection, he notes he collected this pocket in 1967.
