Emerald

34 pierres

No other gemstone offers a green quite like the emerald. One of the four recognised precious stones, it was Cleopatra's favourite and has long symbolised renewal. Its so-called "garden" — those fine natural inclusions — is the mark of authenticity: a perfectly flawless emerald should give pause for thought. Bonnot Paris selects its emeralds at source, notably in Jaipur, the world's foremost trading hub for precious stones: warm, luminous greens from Colombia, deep blue-tinged greens from Zambia, every stone certified by an independent laboratory with any treatment declared in full transparency. To see this green set in gold or platinum, explore our emerald engagement rings , created to order — or compare with tsavorite garnet , the other great green of fine jewellery.

Explorer

Garnet

18 pierres

Garnet is an entire family of colours, far beyond the deep red it is so often reduced to: the electric green of the tsavorite , the mandarin orange of the spessartite , the raspberry hue of the rhodolite . Entirely natural stones — garnet is never heated or treated — they offer vivid colour and remarkable brilliance at accessible price points. Bonnot Paris selects its garnets directly from partners in East Africa and has each stone certified by independent laboratories. A wonderful introduction to the world of coloured stones, and a stone of real character for a piece of jewellery: discover our garnet engagement rings , created on a bespoke basis.

Explorer

Rubies

6 pierres

The ruby is the rarest and most intense of all precious colour stones. Coloured by chromium — which also gives it that unique fluorescence, the inner fire that ignites in sunlight — it reaches a hardness of 9/10 and commands higher per-carat values than any other coloured gemstone. Bonnot Paris selects its rubies directly through its offices in Sri Lanka and Bangkok: Burmese rubies with their legendary pigeon's blood colour, and Mozambique rubies , often unheated. Every stone is certified by an independent laboratory — lead-glass treatment is never accepted. To wear this exceptional red, explore our ruby engagement rings , created entirely to your own design.

Explorer

Sapphire

453 pierres

Sapphire is one of the most sought-after and widely used coloured gemstones in fine jewellery. A corundum with a hardness of 9/10 — second only to diamond — it endures through generations without losing its brilliance, and comes in far more than blue: teal, pink, padparadscha, yellow, green, violet, orange. Bonnot Paris sources its sapphires directly from origin markets in Sri Lanka and Madagascar. Every stone is presented with its treatment disclosure and an available laboratory report (SSEF, GRS, ICA or Bellerophon depending on the stone); diffusion-treated and fracture-filled stones do not meet our selection standards. Choose your gemstone from our curated collection, from Ceylon blue sapphire to Madagascan teal sapphire , then picture it set: discover our sapphire engagement rings , created bespoke in our workshop.

Explorer

Spinel

24 pierres

Spinel is one of the best-kept secrets in fine jewellery. Long mistaken for ruby — the so-called "Black Prince's Ruby" in the British Crown Jewels is in fact a spinel — it is almost always entirely natural and untreated, with vivid brilliance and a hardness of 8/10 that makes it perfectly suited to everyday wear. From flamboyant red spinel to steel grey, vivid pink and cobalt blue, its palette captivates connoisseurs above all. Bonnot Paris selects its spinels directly from Bangkok and Sri Lanka, with every stone certified by an independent laboratory. A refined alternative to ruby , at a gentler price point: explore our spinel engagement rings , created to order.

J'ai contacté la bijouterie Bonnot car je souhaitais un saphir Padparadscha, qui est assez rare. Toute la transaction a été faite à distance et s'est très bien passée. Ils sont très professionnels, à l'écoute et très sympathiques. J'ai reçu ma bague et elle correspond tout à fait à ma demande. Merci beaucoup 😋
