The item is a sterling silver st. Bernadette pendant with a 18 inch long silver curb chain. The chain will have a spring ring catch. I can use different style chains or lengths if you prefer. The medal measures 3/4 of a inch wide or 23 millimeters. The back of the pendant is plain and we can engrave it at no charge for you. The front of the medal says Bernadette Soubirous. This item has to be made so please allow 5 days to have it made before I can ship it. I will provide a nice pendant box.
