Layer of transluscent, vivid blue/green Smithsonite over a dark brown matrix. A label accompanying the specimen from Mark Hay, noted Arizona collector and dealer states that this is the best color he has ever seen for a Silver Hill Smithsonite. Typically, Smithsonite from this location is white in scattered small crystals. Reportedly only 2 pieces like this were ever found. Ex. David Shannon collection. This competition quality specimen is a unique, one of a kind example from an obscure Arizona locality.
