Testimonies

“I am absolutely thrilled with the experience I had with Bonnot Jewelry to create a custom engagement ring for my fiancée.

The process was smooth and enjoyable, and the staff was incredibly professional, attentive, and patient. François really knew how to support me in choosing the stones (size, quality, etc.). Their know-how and attention to detail exceeded all my expectations.
The ring is simply beautiful, perfectly reflecting the tastes and personality of my fiancée!”
Tidiane

“We called on Mr. Deprez to create our wedding rings. From the first date he understood my husband's style. The designs are super well done and the whole team is very attentive to changes to be made if necessary. Mr. Deprez also knew how to adapt perfectly to the budget that was given to him.
The rings are of irreproachable quality. We will be calling on him for other projects without hesitation!”
Océane

“My experience at Bonnot Paris was incredible from start to finish. From the first appointment, I knew I was in good hands.
François took the time to understand my needs and my preferences, and presented me with a selection of stones that were all more beautiful than the last.
The design process was a true collaboration. The designer drew 5 options and was very receptive to my comments. The end result is a custom ring that I love.”
Christelle

“Bonnot Paris jewelry is exceptional. The stones are stunningly beautiful. François is going straight to the conquest of exceptional gems!
Why go to a “famous” jewelry house when François and his team accompany you throughout the process of creating a unique piece of jewelry, perfectly adapted to his tastes and personality?”
