FI's DIL told me she had a broken prong on her E-ring this summer before their Sept wedding. I took it back to the jewelry store (It was bought at store in my town, not her's) and the jeweler asked me what occupation the ring wearer did. She was a dog groomer. Jeweler said chemicals at work and bleach can weaken gold. Bleach leaches into the gold especially bad and the gold is for ever weakened and prone to breaking. I thought this was good info since I don't take my ring off very often.
