The Swan Locket

The Swan Locket is a gift that Derek had giving to Odette as a present with his widowed Mother Queen Uberta. It has the form like a heart and at the middle of the heart it has a picture of a Swan.

Odette wears it to all the four movies as her favorite Locket and she never takes it off. Only in the first movie it's seems that Derek saw it drop on the floor as Odette was Kidnapped by The evil Rothbart. He kept it and as he found her he returns it to her as everyone believed that she was gone only Derek didn't believe she was dead.
