Cisco Adler has given Mischa Barton a promise ring... and it's gotta big ol' diamond in it. She wears the ring on her right hand and has told her friends that it represents the promise of an engagement. Or is it the promise of a promise of engagement. Why is this news?

Mischa's been flashing it to all her friends, saying "Look at my promise ring." She wears it on her right hand so it's not an engagement ring - yet. It's a promise to get engaged. Actually it's more of a "compromise ring." (source)
