Bright yellow sprays and tufts of Haiweeite from 3 to 6mm across, which is quite large for this occurence. with some orange yellow Uranophane. This is an outstanding specimen with good coverage on the face and along the sides. There are funny transparent colorless, worm-like crystals with green tips on this specimen. I have no idea what these are and if you buy it and analyze it, please let me know the result.
