Best Bet: Moon Spike Earrings

Brooklyn designer Erica Bradbury of Species by the Thousands is best known for her darkly inspired brass and bronze jewelry – past creations have been modeled after cave rock formations and macabre Edwardian imagery. Her latest collection launches this week, incorporating cast bone and vertebrae pendants, as well as  summer-ready seashell cross-sections. These curvaceous Moon Spike earrings are a pared-down standout. The slender crescents are delicate, but edgy without resorting to spikes or skulls.

Species by the Thousands Moon Spike earrings, $90 for brass/white bronze; $140 for sterling silver online.
