Cavity in limonite lined with lustrous pastel green translucent chisel shaped cuprian adamite crystals on a bed of drusy clear calcite crystals. Awesome under the loupe. The adamite fluoresces a nice lemon yellow color, but I could not capture it well in the photo. None of the photos do justice to this beautiful specimen. Perfect condition. Measures 3.5 x 3 x 1.5 inches (9 x 7.5 x 3.8 cm).
