This is an unusually robust example of this rare pseudomorph, that for some peculiar reason actually occurred in abundance at this one locality in several pockets over the years. The crystal is large, sharp, and complete all around.In contrast to some of the more modern examples, it has an attractive look to it, earthy brown but with style. It is associated with some micro black species, as well. ex. Jim White collection

The spear like crystals of ernstite, a rare manganese, iron, aluminum, phosphate, after childrenite, have given this specimen a burnt umber appearance. Brazil’s pegmatites are the receptacles for an incredible number of fine secondary phosphates. But most crystals of this material are slender and simply unappealing. This robust crystal, however, really is dramatic.
