Known for its glittering crystals and shimmering baubles, Swarovski is branching out with its first stateside concept shop, which includes a full-service restaurant and a hang-out space. The focal point of the block-long boutique is the "library of light," a selection of 2,000 stones (in every shape, cut, color and material imaginable) that can be purchased individually ($8--$22). Pick up jewel settings ($2--$12) and tools ($3--$30) and craft a one-of-a-kind creation downstairs in the sleek lounge. It's easy, we swear. But if you're not into DIY, order bespoke jewelry by customizing a piece from the ready-to-wear collection at no additional cost.
