diamond in rough

Unrefined but valuable

A diamond in the rough is someone or something with excellent qualities that aren't immediately apparent—potential obscured by an unpolished exterior.

The phrase comes from uncut diamonds, which look like ordinary stones before being cut and polished: The scout saw a diamond in the rough in the young pitcher.

Sometimes shortened to a rough diamond, especially in British English.
