Testimonials

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

"We called on Monsieur Deprez to create our wedding rings for our wedding. From the very first appointment, he understood my husband's style. The designs are very well done, and the whole team is very attentive to any changes that need to be made. Mr. Deprez was also able to adapt perfectly to the budget he was given.
The rings are of impeccable quality. We'll be calling on him again for other projects without hesitation!"
Océane

"I am absolutely thrilled with the experience I had with Bonnot Joaillerie in creating a custom engagement ring for my fiancée.
The process was smooth and enjoyable, and the staff incredibly professional, attentive and patient. François really knew how to guide me in my choice of stones (size, quality, etc.), and their expertise and attention to detail exceeded my expectations.
The ring is simply magnificent, perfectly reflecting my fiancée's tastes and personality!"
Tidiane
