Interestingly, when you zoom in, particularly towards the top of the image, you can also see tiny white hexagonal crystals (likely mimetite) and rounded green crystals (likely copper-bearing adamite or zincolivenite). Neither species is listed in Mindat. Ex Ian Graham. Width of view 3.5mm. Stack of 50 images.
