SOWBELLY AGATE (VEIN AMETHYST) POLISHED SLABS
Sowbelly Agate, also known as Vein Amethyst, is a formation of banded chalcedony, quartz, and amethyst. It's especially unique because most specimens contain dendritic native silver branching throughout the chalcedony! This gorgeous material comes from the Last Chance Mine in Creede, Colorado.
