My husband bought my ring 3 years ago. It became very hazy and would not clean up. I was embarrassed to wear it looked so bad. I took it to my local jeweler and he told me my CZ was very scratched. I was so shocked I told him my husband had paid a lot of money for the ring. My husband contacted Nexsus and they said it was not under warrenty anymore because someone else had worked on the ring. He told them all he cared about was the stone. So they put a new stone in the ring. But the new stone is starting to look like the old stone. We are sick about what my husband paid for the ring and it is always going to look crappy. I have a 1200 dollar CZ.
I would not recommend these diamonds to anyone. The company is a scam and they won't cover their diamonds.
