I wear a Chinese jade archery ring about half the time. If I'm going to do any shooting it's just easier for me to not lose it if I keep the ring on for the rest of the day, but I never put it on if I don't plan on putting holes in targets. It's seen as ornamentation by those around me, but I don't really mind that.

As an aside, mens wedding rings only gained prominence after WW2. Immediately before the Great Depression men received a ring in less than 1/5 of marriages. Immediately after WW2 1/2 of men wore wedding rings in their, and now about 4/5 do. Rings, like wristwatches, were considered effeminate and had no place in a man's attire. That they both are now worn shows how fluid fashion can be.
