Mondiamo Makes It Easy and Lucrative


I was incredibly nervous to send my expensive diamond to Mondiamo. After finding many positive reviews online, I decided to give it a try mostly because Mondiamo is related to Blue Nile.

My experience with Mondiamo was incredibly positive. They called, responded to both calls and emails in a timely manner, kept me informed, and really went out of the way to answer all of my questions and make me feel comfortable.

In the end, I received 32% more for my diamond from Mondiamo than I was being offered at home.

If you are looking to sell a diamond, I highly recommend Mondiamo.

This process was so easy, it can be an emotional journey when you return a wedding band that is no longer needed. This process made it easy to make that decision and comfortable that it was going back into good hands! Thank you
