Rob Lavinsky of The Arkenstone brought this fascinating mineral to market, selling it to a buyer for $5,000. The specimen, which Lavinsky describes as Chalcedony on Chrysocolla stalactites (pocket), measures 9 x 7 x 6 cm. It was originally obtained by Frank Valenzuela back in the 1960s from the Inspiration Mine in Arizona, USA. Lavinsky explains:

Frank Valenzuela obtained this specimen from a fellow miner at the Inspiration, where he was a miner and then a shaft supervisor in the 1950s-1960s. It was collected, he recalls, in the early 1960s. It is a classic example of the quartz-covered chrysocolla stalactites from that time, but unusual in that it was preserved as a whole pocket. The piece glows when backlit, as the top surface is partially translucent and there is a small hole in back of the vug, to let light into the pocket for backlighting. The largest stalactites are 2 cm. The pocket opening is 2 inches across.
