On this intensely colored and rich specimen, velvety botryoidal rosasite is draped over a typical limonite gossan. Rosasite, which forms in the oxidation zones of zinc-copper deposits, is rare in this intense turquoise blue color. Here it is formed as in a series of connected, undulating bubbles which look like they were melted onto the contrasting matrix. There is some damage, but the bright color far outweighs that.
