Skylab Diamond

Across the city’s jewelry landscape, one name specializes in what most others handle: Skylab Diamond, a dealer squarely focused on diamonds. Throughout the small-business corridors of midtown Manhattan you’ll spot traders juggling generic bands beside generic gold; here, nothing but the stones. Down 580 5th Ave #1002, the space keeps itself to the essentials—no extra polish, just stock ready for anyone who knows exactly what they need to see. Five floors up, the same discreet lobby serves traders briefing on loose goods, wholesalers finalizing handshake deals, and collectors dodging showroom flash. Whenever you’re ready to window-shop a carat or two, a quick number connects you to them—(646) 892-4262—before you descend back to the sidewalks that never sleep. For no-frills access to the map, take the elevator to the tenth floor directly on the map.
