I have never seen so many Joaquinites on one specimen. And these are excellent crystals to 1mm. Oh, there is a 1.3cm Neptunite on top but the black background hides it. There is also just a little bit of a partial Benitoite near the outer edge.

This is mostly a good Zippeite specimen with bright yellow pulverulent coating throughout matrix. The Johannite is suspect, and could very well be zeunerite or just Malachite.
