For those who prefer to go darker in terms of fashion and accessories, what better than black diamonds? Especially in the form of the batmoth? It looks like a butterfly, but the name is irresistibly edgy.

Made by Stephen Webster, the ring has a quarter-carat of black diamonds set in 18k white gold, and is a nice way to keep your sparkle more muted. It sells for USD $1800 at Fragments.
