This specimen is one of the best I have seen from this classic Brazilian find of the mid-90s, with unusually large, individual crystals to almost 1 cm in size. It was purchased from Carlos Barbosa at the time by a privat eEuropean collector of rarities, based on these unique qualities. The crystals are translucent and you can see individual faces on them, as opposed to the usual style for the material: small, 3-4 mm crystals all jumbled together and with little relief. A superb specimen!
