keweenaw ring apache jasper and sterling silver ring
by Felicia Parsons |
| Copper is one of the few
minerals to occur naturally in an uncombined form --- meaning not part of an
ore. The Keweenaw copper deposits in Upper Michigan were major copper
producers in the 19th and early 20th centuries, and are the largest deposits
of native copper in the world. You can see the vein of copper glinting in
the river of white quartz that surrounds it in this stone. US size 4
$125 The stone comes from Michigan and was hand cut by Gary Wilson. |
