large Montana agate pendant, wrapped in bare copper

This is a big, beautiful Montana agate cabochon wire wrapped in bare copper and ready to wear. The necklace is on an adjustable waxed cotton cord. Montana agate is found in the gravels of the Yellowstone River. From a website called Crystal Viden, "Behind the swathes of tan and yellow, you’ll find bits of iron oxide, black manganese oxide, and nodes of dark-colored Chalcedony. These inclusions can take the form of round globs, thin bands, or tree-like dendrites. Every piece is unique, adding even more distinction to this already sought-after stone."
