Most guys don't have a lot of experience with the finer points of ring wearing etiquette.

That's not a problem - because if you're reading this article you're about to learn more in 5 minutes than what 95% of the population knows.

There are many traditions regarding jewelry in general, and rings in particular. Use them to make a statement without opening your mouth.

 
1. The Little (Pinky) Finger

This is often the first choice for a man who wants to wear a "statement" ring.

Pinky rings have a couple of advantages: they don't have religious or cultural associations in most cultures (unlike the ring finger), and, like rings on the fourth finger, they don't touch or interfere with the index/pointer finger at all.

 2. The Fourth (Ring) Finger

In the US and much of North & South America, the ring finger is most commonly associated with wedding symbolism: a band on the right fourth finger indicates engagement, while a band on the left fourth finger indicates marriage.

 3. The Middle Finger

Apart from the obvious hand gesture, the middle finger is your largest, boldest finger.

Rings worn on the middle finger are surprisingly uncommon — in part, that's because it's adjacent to the index finger, and anything bulky can be quite a hindrance to fine manual tasks. It's best to keep things small and simple if you're wearing them on your middle finger.

 4. The Index or Pointer Finger

There's a natural instinct to keep the pointer finger clear, since we use it more than any other digit (except the thumb), but it turns out that a ring on the finger doesn't interfere with it as much as one on the finger next to it.

 5. The Thumb

Thumb rings have a slightly outlandish feel to people who come from conventional North American culture, but they're actually reasonably common world-wide. In most societies a thumb ring on a man is a sign of wealth or influence, and they tend to be broad or bulky to reflect that (also to fit comfortably on the thumb, of course).

A thumb ring is also often the natural choice for men who want to wear multiple rings on the same hand, since it's at least somewhat distanced from the others. A wedding band plus a pinky or middle finger ring can get quite crowded, both visually and physically, whereas a thumb ring gives everything some space.
