This highly secrative and exclusive organization is one of many underground secret societies on Mercer Island.

The origins of this group have been traced to 13th century Scotland, where women of the royal family and other noble ladies of the court founded the Sochai d' Diamant Dubh (the Gaelic which translates to: Society of the Black Diamond). According to government documents and papers recovered form the Scottish Ministry of Foreign Commerce, a member of the society moved to American during the late 1800s where she founded a branch of the group. The Black Diamonds have appeared in small affluent suburbs around America ever since.

Little is known about the Black Diamonds (a.k.a. Diamond City,) but the group reportedly consists of senior girls in the class of 2009. New members are required to undergo a grueling 2 week initiation, but the benefits of the sisterhood are rumored to be enviable. In accordance with the ancient Scottish tradition of the society, the Black Diamonds are primarily in existance to continue the bonds of love and friendship amongst the Senior Babes through their University years, and through the rest of their lives.

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?"
