An aesthetic, old-time copper specimen from Michigan's famous Copper Country. A showy, ribbed, fan-like spray of elongated spinel-twinned crystals are tipped with tetrahexahedral crystals. The "fan" rests on a cluster of very sharp, what appears to be, elongated, twinned octahedral crystals, a much less common copper crystal form. The overall presentation of two DISTINCT copper crystal forms and nice patina make for an excellent Copper Country specimen. Ex. George Elling Collecton.
