Fluorite Sphalerite Galena and Barite

At first glance one might dismiss this specimen as a “leaverite”. However, once in hand it is fascinatng. I believe this piece was either part of a wall or floor. It is comprised of layers of massive fluorite and host rock. On the “bottom” side are small well crystalized purple fluorite crystals, indicating a small seam was likely. The top of the specimen is a salad of minerals. Fluorite breccia, sphalerites forming amongst small galena crystals, and beautiful blades of white to blue barites, looking like feathers.
