I have to really agree that Omni Jewelcrafters have no customer service skills and have poor products.
I have had my engagement ring for less than a year and my side diamonds have fallen out on four separate occasions. On one occasion the diamond fell out less than 24 hours after I got the ring fixed. I asked for the ring to be fixed and they told me to stop crying because I was going to get the ring fixed and these were Jack's words. Jack is the owner of all the Omnis. I asked him if I could get the band replaced and he said no problem, but when I got the ring back they did not replace the band. They told me they were going to replace the band and if that is what I wanted. However, now they say they are never going to do that.
Also, warranty is an issue. They keep changing the warranty rules. First, its lifetime and now they say its two years. I asked for the warranty on paper, but they say their word is good enough.
NEVER SHOP THERE!
