Colored red by cuprite and green by malachite, this aesthetic copper specimen is extremely well crystallized. The largest copper crystal measures 4.0 cm in length. But the highlight of this specimen is the incredible, spear like, crystal, exhibiting elongated, possible tetrahexahedral twinning. This is a fine old Michigan specimen.
