Beautiful locket. 30 mm in diameter and is 316 stainless steel. It has pink swarkovsky crystals around the outside and an interchangeable locket plate. I also have teacher charms available too. Apples, boys, girls, globes, I love to read, and book charms. Fun way to welcome new staff, or for a retiring teacher, Teacher of the Year makes a terrific gift. Payable through Paypal. Actual physical good will be mailed to your address, so please include when paying. Thank You!
