This thumbnail specimen of plancheite consists of dozens of radial sprays of acicular crystals. The crystals (in tiny puffballs) are a perfect turquoise color, and are translucent. Also on this specimen are radial sprays of a bright green mineral, which I suspect is brochantite. The tips of both minerals are frequently accompanied by an acicular white mineral, which I cannot identify, and which obscures the deep colors of the underlying minerals. With a loupe, the brightness and clarity of the plancheite (and brochantite) is apparent.
