A rare, superb and very aesthetic pseudomorph specimen from the Mount Gunson Mine of South Australia. The contrasting gossan matrix holds an outstanding, essentially undamaged, jackstraw cluster of lustrous malachite pseudomophs after sharp, isolated atacamite prisms. These were large atacamite crystals for the locality and reach 1.2 cm. According to one of the labels, the specimen was collected in 1994. Ex. Matthew Webb, a well-known Australian collector and Bruce Carter Collections. I have never seen another example, nor even of this replacement before.
