To pull a Rachel Zoe, when we saw this Yochi Green Aggie Cuff ($66), we moaned, "I DIE!" in spasms of fashion-induced ecstasy. A 2-inch chunky rainforest green agate, laced with ribbons of copper and obsidian, perches across a sleek, slim gold cuff wrapped with gold wire. It's a total on-its-own accessory piece, too; you don't need any other jewelry when you wear this statement-making stunner.
