The pictures do not do justice to these shimmering, lustrous, gemmy crystals (to 1.25 cm), perched on contrasting matrix. They have a golden color and internal shimmer that is simply amazing for the species and the locality. I have never seen the like. Neither had Luis Menezes, from whom I bought the best two specimens he had for sale from a very small lot obtained some months ago in Brazil. 6 x 4 x 3.25 cm
