Oak Island was one of the last lighthouses built in America. The concrete used during construction contains paint, so the structure will never need repainting. The lighthouse is still in service and is manned by the U.S. Coast Guard. The beacon produces 2,500,000 candlepower and shines over 24 nautical miles during times of darkness. The lighthouse has 134 steps to the lantern gallery level. This Charm was hand designed with great detail by Linc Mason. It has a hollow back and is 1″tall.
