Client Stories

I just wanted to take a moment to thank you for making I do Now I Don't. I found this page and was skeptical at first. Then I found a ring I knew was my dream engagement ring. The seller and I talked and it was very easy to get all the information I needed about the ring. Then the staff was so resourceful and courteous. The process was quick and I got my dream ring for less than half of retail. The ring is even prettier in person. I tell everyone I know about I Do Now I Don't. Thank you.

After several purchases from this amazing site, I will never shop retail jewelry stores again! There is a huge variety of diamonds, as well as other jewelry. It does take a bit for them to ship items out, so patience is a must. They take time to check the items for quality before they ship them to the buyer, and I have never been let down! I will never buy jewelry from anyone else besides them.
