The item is a sterling silver Saint Barnabas pendant with a 18 inch silver chain. The chain will have a lobster claw catch. The pendant measures 3/4 x 1/2 inches or 1.905 x 1.27 centimeters. The back of the pendant is plain and we can engrave it at no charge. This item is made to order so please allow approximately 4 days before we can ship it. I will supply a pendant box. He is the patron saint against hailstorms.
