From a famous find of 2006, this is a superb example of spinel-twinned copper crystals from a one-time erratic find. All came from a single large boulder found by Stan Esbenshade, and carefully trimmed out. This is, for the size, unusually thick - much more robust than most. Note the layer of secondary crystallization like wings along most of the central spinel twin. The clear spokes of the central twinned copper crystal provide several sharp flanges to give it added visual impact and size appeal. This was a onetime find, and now these are hard to find for sale today. This is a complete floater, terminated all around and formed in a spongy mass of strange copper float material.
