Mull agates are generally rather small, ranging from about 30 to 50mm in most cases, although larger examples do occur. A large majority comprises clear and banded chalcedony, and these frequently possess the most exquisite patterns. The agates found here are usually uncracked and show no colour apart from some with a pale honey tint.
