a social/fashion trend in recent years where American women (especially ditzty teens and freshly-turned drinking age hotties) seek out any/all African-American males. Said chicks then IMMEDIATELY "go public" with their 20 carat "black diamond" by spending every second of their lives 'showing off' their man (or baby-daddy, or whatever she passes him off as to the entire world).
"Did you see that skanky blond booger-hog struttin' around the club showing off her new Black Diamond, all-like she was the f------ Queen of England an' shit?"
