BLR119 Black River Agate Nodule
Black River Agate from Argentina is a naturally water-worn agate prized for its banding and history of geological movement that creates these partially-tumbled nodules. This specimen features white and yellow banding in a dark brown nodule. The back of the agate has another, smaller section of banding, which uniquely shows how the banding formation changes throughout the agate to be in a different position on the other side.
