Yes, how does some small little mining colony in an asteroid belt (or just 55 Cancri e, just because it would be hilarious to have the Feds and the Union fighting over an [i]entire planet of diamond[/i]) being contested by a Federation mining expedition sound?

Although I admit planet sized diamond sounds fun even if not as likely to start a feud, IMO.
