Les Néréides

Being the sister city to Paris, it was only fair that the first U.S. opening of the high-end Parisian jewelry brand be in Chicago. A true definition of "je ne sais quoi,"the brand is known for elaborate, playful costume jewelry. Expect to find necklaces, bracelets, rings and earrings featuring handmade, hand-painted tiny ballerinas, intricate flowers, sea creatures, and even penguins on bicycles. If you're looking to splurge ($60-$800) on a unique, wearable work of art, look no further.
