Yellow to yellow-brown, vitreous crystals of oxyplumboromeite to 1mm densely cover the surface of this piece. Minute, off-white microcrystals of cervantite are found in numerous, tiny vuglets in the quartz matrix, and blue-green, clusters of euhedral, 0.5mm, scorodite crystals occur locally. Interesting association from an unusual Brazilian locality. Ex. Paulo Matioli collection.
