Mondiamo was a breeze to work with...their communication was top notch and the process could not have been any smoother. I highly recommend this company!
I had limited information about my jewelry and they were still able to work with me. I also appreciated the quick turnaround in looking at my jewelry, providing an offer, and providing payment upon acceptance.
The process was very easy, response from Mondiamo was timely, I felt very confident in their service. Everything went as promised from estimate range to check arrival.
I truly enjoyed every stop of me selling my diamond ring! They make it completely effortless on your part!... I would highly recommend using Mondiamo.
I really appreciate how simple, fast and fair the whole process was. I highly recommend Mondiamo and I can’t say enough about the customer service and how transparent they are.
I was skeptical at first, but Mondiamo exceeded my expectations at every turn. From the offer process, to the patient customer service, to the website— Mondiamo is the way to go.
