I wear mine everyday but take them off as soon as I get home. I take mine in every 6 months to have the prongs checked and if I needed them repaired or the rings sized, the work is free thanks to the warranty DH bought when he bought the rings (I think it cost him $100 at the time). If I lose the diamond in that 6 month period, they also replace the diamond for free. If I don't get the rings checked on time and lose the diamond, we pay to replace it.
OP - Can you get a new set of prongs?
