Atelier Bijouterie Diplomate — créations sur mesure

Custom creation — Plateau Mont-Royal

Custom Made

From idea to one-of-a-kind piece.

It all starts with a conversation.

Ralph Kelendji has been a master jeweler and diamantaire for over 60 years in the heart of the Plateau Mont-Royal. Every custom piece begins with a meeting — to understand your story, your style, and what you wish to convey.

Whether it's for an engagement ring, a wedding band, a commemorative pendant, or a completely original piece, Ralph guides you every step of the way. Our creations are based on the same artisanal craftsmanship as our repair workshop — every detail is handcrafted. Contact us to make an appointment. No two pieces are alike.

The creation process

The Consultation

We discuss your vision, your budget, the occasion, and the desired materials. This meeting is free and without obligation, in-store or by phone.

Design

Ralph sketches your piece by hand or prepares a digital rendering. You approve every detail before any work begins.

The Model

A wax or resin prototype is created to validate the proportions and comfort. You can view and try it on before the final casting.

Shaping

Each piece is cast, set, polished and finished by hand in our on-site workshop at 1144 Mount Royal Avenue East.

The Play

Your unique piece of jewelry is ready. Delivered in a Diplomate case, accompanied by a certificate of authenticity and covered by our 1-year warranty.
