Rosieresite Botryoids

Ex. Rock Currier

A rare, complex lead phosphate hydrate that is not well characterized. From a peculiar locality. Nice thumbnail specimen consisting of small, yellow-brown to grayish, grape-like botryoids. Shows concentric layering on the backside with a radial structure nucleating on sphalerite. This piece may provide good material for further characterization. Eric Asselborn label.
