Moonstone

A Moonstone is a very smooth stone. It is used for jewelry in modern days and used as necklaces and treasure in the days of pirates. When Jack Sparrow and the crew of the Black Pearl visited Sri Sumbhajee's palace, Carolina was given a Moonstone from Sri Sumbhajee's wife Parvati. She told her that she would let her keep it if she and the crew were able to find Sri Sumbhajee's assassin witch they did so Carolina was able to keep it.
