An aesthetic and superb copper specimen from the famous Copper Country of Michigan and the Mullane Collection. A super-sharp, complete all-around, 2.2 cm, tetrahexahedral copper crystal is set on a box-work bed of smaller copper crystals. The copper crystal "tail" is truly dramatic and the piece has two different colors of coppery patina - beautiful. This is classic, old-time material from this renowned locale. The large, sharp crystal is especially noteworthy.
