Joomi Lim. Hematite Double Spike Ring. Clean lines and towering spikes make this cocktail ring a serious knockout. You might be used to seeing these chunky links in her deliciously louche bracelets and necklaces, but Joomi Lim attaches them to a hematite-coated brass ring and suddenly they become an architectural marvel, especially when topped with silver-tone spikes that flare out into a wicked "V". Stack it up with more delicate styles for a study in contrasts or keep your look sleek and tough by piling on more of Joomi's signature bracelets. Made in the U.S.A.
