A stunt double can be a good idea. Especially for traveling. I just don't know how long it will hold up though when sporting and other rough conditions. And once it starts to look damaged or a stone chips or gets scratched you'll just toss it and be in the same situation as you are in now.
I'd just get a plain palladium or platinum band ring and be done with it. That's what you wear and then no worries about even cheapo stones falling out, collecting dirt under the gallery, chipping and the like.
