We bought a wire ring, and bangle in 18 k white gold for our 20 years anniversary, but sadly my husband ring after wearing it for 6 months, it's discolored, it's turn to yellow. I brought the ring back to the store in San Diego to get it fix, they told me I have to pay $100 for repair. Why do I have to pay when it not our fault. The sale representative keeps saying I'm sorry, I can not do anything. I tried to email them, no response. It's very disappointed,
