Ideas for a magic 项链 design! A 支持 for everyone who helps:)

I'm 写作 a story involving a magic 项链 but I have no idea what to make it look like. So I was wondering if 你 could help me find some.

- I would prefer if the 项链 has a red stone 或者 revolves around hearts in some way, but anything unique 或者 creative looking will do.
