At Bonnot Paris, every stone is selected for its rarity, clarity and ethical provenance, ensuring full traceability, exceptional quality and fair pricing.

Contrary to popular belief, sapphire is not only blue: it exists in virtually every colour of the spectrum, with the exception of red — which is called a ruby, even though it belongs to the same mineral species (corundum). At Bonnot Paris, we work with seven main colours:
There are also white sapphires (colourless), black sapphires, and fancy sapphires in intermediate hues (orange, golden-brown, blue-green). A remarkable optical phenomenon: certain sapphires display a colour change depending on the light source (blue in daylight, violet under incandescent light) — known as colour-change sapphires, and among the most valuable of all.
This chromatic diversity makes sapphire one of the most versatile gemstones in fine jewellery — each colour with its own rarity, its own symbolism and its own price per carat.
Every creation begins with a personalised consultation — in Paris, in Angers, or by video call — to understand your wishes, your story and your budget.
Our experts guide you through the selection of stones and the development of your jewellery design.
Our designers then produce several sketches so you can visualise the piece.
Once the stones and design have been approved, our master jewellers craft your creation by hand in our workshops, to the highest standards of excellence of Maison Bonnot Paris.

Yes, all our stones are certified by renowned laboratories such as Bellerophon, ICA GemLab, London Gem Lab, and others, guaranteeing their authenticity and exceptional quality.

Delivery is carried out in person in Paris or via a specialist carrier, ensuring a secure, insured and fully reliable shipment to its destination.

Lead times depend on the complexity of the piece, but you should generally allow between 4 and 8 weeks after final design approval.
Thanks to our offices in India, Sri Lanka and Bangkok, at the heart of the markets and mines, we take the time needed to select the ideal stone, perfectly matched to your expectations.

Yes, Bonnot Paris offers a recycling and transformation service for your existing jewellery.
We can reuse the gold from your current pieces to give it a new life, in a jewel designed especially for you.

We work with many clients across France and internationally on the creation of bespoke jewellery.
A video consultation is first arranged to understand your wishes, expectations and project.
From there, a personalised follow-up is provided via WhatsApp or email, to guide you at every step.
We send you detailed photos and videos of the selected stones (or jewellery), so you can feel fully confident in your choice.
You are also welcome to share, by message or image, your inspirations, questions or doubts — we remain attentive throughout the entire creation process.
