Item Details
Description
NATIVE COPPER
Keweenaw Peninsula, Michigan
The ancient lava flows of the Keweenaw Peninsula were produced during the Mesoproterozoic Era as a part of the Midcontinent Rift. This volcanic activity produced the only strata on Earth where large-scale, economically recoverable 97% pure native copper is found. This is a terrific specimen of wonderfully twisted and textured form, with multiple apertures, a rich orange-brown color, and plenty of metallic sheen, along with aesthetically contrasting areas of green oxidization, approximately 5 x 4 1/2 x 2 3/4 inches overall.
