Creedite

Although the mineral Creedite is common, excellent examples are not. This is a great example all around. It has a good orange color, matched with bright clear crystals. It is just the right size, and has a "well placed," ball in the center that makes it quite aesthetic. It's in fine condition, esp. since virtually all creedites are damaged (many occur on the ceiling of the mine and have to be pried loose with a pole and then hopefully caught as they fall (like spiked coconuts falling - yikes!). This one has a barely noticeable spot on the far left side where three or four small crystals are missing, which is nothing for a cluster of this size. 

Creedites are found in a highly mineralized clay (that affects their color), within a Breccia Pipe, that had injected hot solution that later crystallized as Creedite. Mining these is fraught with danger, as cave-ins are quite common, and have finished recent production (according to Mike New).
