Expensive quality for less 👌🏻

Absolutely amazing . My engagement ring was purchased online - great price and took to expensive jeweler and they priced it almost 3x as much as I paid. We got my wedding band later after emailing with Dino and he found a band that matched my ring and uploaded a video of what it would look like so we could see it before paired with my style of ring. Great shipping , always does next day air and it’s packed great. Would recommend highly !

Outstanding quality and service

We ordered a custom, 5-carat, u-prong eternity band. The ring is spectacular. The communication with Dino was perfect. And when we needed a slight adjustment in size, the customer support was spot-on.

I will share the message I sent Diamond Mansion on eBay which had a word limit or I would have written even more.
Dude,
Thank you! I wish I could leave longer feedback for the review. I had the ring appraised by The Jewelery Appraiser- Debòrah Ann Villepigue in Manhasset NY. She has appraised engagement rings for Lady Gaga and Paris Hilton. She could not say enough nice things about the center/side stones. She was thoroughly impressed by how the ring was crafted/set, specifically noting the importance of this for princess cut diamonds. It appraised for a little over $7,800 after taxes and she was VERY surprised by how much I paid. I say all this because I was incredibly reluctant to purchase a $5,000 engagement ring off eBay but did so because of your return policy and the strong advice of my gfs mother. She sold jewelery on eBay years ago and said its very hard to have ur rating selling jewelery on eBay. Even when I received it I said, nope too nice/good to be true which is why I paid $270 to have it appraised by “the best.” Dino! Cant thank you and your team enough!
Best Regards,
Ryan D’Alessandro
