Mineral specimens from the copper-zinc Antler Mine of Mohave County, Arizona are very uncommon and very rarely available. This striking specimen features a crust of iridescent, botryoidal smithsonite on a matrix of massive smithsonite. The iridescence is a mellow peacock-blue to magenta. Very unusual and seldom available material from this locale and the Dennis Mullane Collection. Accompanied by an older, 1950-early 1970s Burminco label.
