rough diamond
Uncut precious stone
A rough diamond is a diamond that hasn't been cut or polished—valuable but unrefined.
The phrase more often describes a person whose good qualities are obscured by crude manners or appearance: He's a rough diamond—gruff and unpolished, but genuinely kind.
The American equivalent is "diamond in the rough."
