Hey man. Got a solid gold Rolex and a silver knuckle ring you've been wanting to wear at the same time? Mixing metals may seem a tricky task, but our breed of metallurgy is easier than it seems. You may realize the strong positive effects of smartly mixing taboo colors like brown and black in a look, and now you're trying it with jewelry. There are a few ways to go about it.

The easiest way to start is to find a piece of jewelry that's done the mixing for you.

1. When you've got knives slung around your neck, no one will question the matter of silver and gold together. Surface to Air

2. A blackish silver with drops of gold deepens the mixture with an old time air. Stephen Webster

3. Hammer out gold atop a silver setting for a ring that kind of resembles a hand drum. Henson

4. Hey bulldog, get royally charged with a crowning cuff link. Tateossian

5. This chain linked cuff has a gold man out. Maison Marin Margiela

To bridge the gap, you could try a little rustiness. Like this cuff by Dsquared2.

When working with a multi-tonal look, you're at liberty to mix it all up. These runway looks from Lanvin, Alexander McQueen and John Varvatos show how mashing up tones can be rugged, sexy and just plain cool. For the jewelry, start with gold cuff links and a silver watch when going for the brown and black suit look. If you've got mustard and gray going on, go gold bracelet, silver ring.

Will you do the mash?
