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 a complete floater, terminated all around and formed in a spongy mass of strange copper float material. This is a particularly gracile and elegant, slightly curving, specimen composed of a central twinned crystal from which outgrowths shoot to the sides. This was a onetime find, and now these are hard to find for sale today. Classic!
