Dark gunmetal has never looked better. The Chrishabana Gunmetal Diamond and Cage Necklaces hit oak recently and are particularly good for men’s accessorization (they are actually unisex). Full of angles and dark, gleaming metal, these Chrishabana pieces have a cool don’t-mess-with-me vibe. Spikes are there but aren’t played out, and the price is right. Lobster clasp and a 16″ chain.
