I don't usually go for man jewelry. It's a tricky look to pull off because it tends to look affected, but in this case I'm making an exception. I'm a huge fan of the Black Diamond Wrap Bracelet from Ruby Kobo's spring/summer 2012 collection.
Yuvi Alpert, who designs the men's line, always mixes soft organics with harder, more geometric lines, which is a perfect combo platter of sophistication and masculinity. His designs always complement the wearer and don't distract from the rest of his look; the result is an understated elegance that never appears forced. The bracelet is made with black diamonds, 14K-yellow-gold findings, and a natural linen-cord band. $1,050; rubykobo.com
