What is Banded Carnelian?
Banded Carnelian is a semi-precious stone prized for its beautiful yellow, orange, or amber bands combined with white. This effect is created by combined layers of Carnelian and Agate, which are both varieties of the mineral known as Chalcedony. Most of these polished stones are mined and produced in Botswana.
