That isn't a bad idea. It would discourage people from constantly changing rings because they'd have a chance of desting.
Say 3% chance each time it's worn
I might even take it a step further by allowing people to set an "owner" on a ring. The owner would then only have a 1% chance of it desting per wear, and anybody else (say a looter or somebody who borrows it) would have a 5% chance of desting.
Or they could keep it at the 3% and share. Or something similar to that. I think the higher the skill of the person making it, the less the chance of breaking as well.. perhaps a newbie crafter's ring might have a 10% chance of breaking per use.. or something like that and be less effective.
