A fine, rare, large cabinet combination specimen from Santa Eulalia and the Dave Stoudt Collection. Both sides of the vuggy, 3-dimensional, very sturdy, sintered gossan matrix are richly covered with lustrous, translucent, gray willemite botryoids. The scattering of glassy hemimorphite blades to 1.5 cm is an elegant accent to the botryoidal willemite. Chalcophanite is an uncommon zinc, iron, manganese oxide, but is very rare at Santa Eulalia. The large "V" of sparkly, grape-like clusters of botryoidal chalcophanite on the front of the piece is very noteworthy. This Santa Eulalia specimen comes with a label with concise mine locality information, indicating that this is, indeed, a significant, large and rare specimen.
