A remarkable specimen on close exam because it has stout, 3-dimnensional, real crystals of the mineral instead of the usuaul needlelike acicular crystals we normally see! on them are perched a few small crystals of vandenbrandeite, as well (darker green). Very important, if subtle, specimen. originally priced at, gulp, 2000, indicating he paid a lot for it. amortized down here, though!
