We’re going to the dark side for today’s happy hour. This week’s cocktails are decidedly dark and make use of juicy blackberries. While this Black Swain-inspired martini is surprisingly sweet, the David Yurman Onyx and diamond Wheaton ring is imposing and seductive. We love the oversized slab of stone, especially its checkerboard facets, and the sprinkling of diamond accents adds the perfect amount of light. Cheers!
