I know from experience, that engagements don't always work out. I've proposed twice and have had to return the ring twice.
The first time, I bought the ring at a store in the mall. When I was buying the ring, the service was great, but when I tried to return it, it was horrible! The customer service line was no help and when I would go back to the store, they would give me the run around.
The second time, I bought the ring at Ziva. I was nervous because I was buying online, but I got a good deal so I went through with it. Plus, I was able to call them up several times and asked lots of questions. They were really helpful and friendly. When I would chat with them on their site, it was the same people I would talk to on the phone, so that was nice. They got to know me really quick.
When I had to return the ring, I got the exact same attention. It was great. They explained the return process and how to package the ring. They just took it back, no questions asked. Well, actually they did ask if it was due to being disappointed with the product, to which I honestly replied no. More like disappointment with the ex-girlfriend.
I know that if I ever try to get engaged again, I will choose Ziva for sure.
