Copper ("spinel twin")

Item Description

From a famous find of 2006, this is a great 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 more robust than most. The crystals themselves are notably sharp and well-formed with beautiful form all around. Note the tiny layer of secondary crystallization like wings along most of the central spinel twin. The running lines of the central twinned copper crystal provide several sharp flanges to give it added visual impact and size appeal. This was an isolated 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. This one is valued at $400.
