Invest with complete confidence. We offer comprehensive support and security for every investor:
Every stone is accompanied by a certificate issued by a recognised independent laboratory (LGL, GRS, ICA, Bellerophon…), attesting its origin, treatment and characteristics. An essential document for any valuable asset, it guarantees the traceability of your stone and facilitates both resale and inheritance.
From stone selection through to the final details, our jewellery dealers guide you at every step. You benefit from personalised expert advice to make the right choices and bring to life, with complete peace of mind, a creation conceived for you.
Authenticity is at the heart of everything we do, from the ethical provenance of our stones — sourced directly, with no intermediary — to the transparency of our pricing and our relationships. Every stone is natural and certified, with no undisclosed treatment.
At Bonnot Paris, we bring decades of expertise in fine jewellery to the pursuit of the most exceptional and exclusive gemstones. Each stone is carefully selected to offer you not merely a gem, but a true work of art.
Investment plans tailored to your financial goals and aesthetic preferences. Our dealers work with you to define a bespoke strategy, from the selection of individual stones to the gradual building of a gemstone portfolio.
Through our direct presence in Sri Lanka, Bangkok and Jaipur, you gain first-hand access to rare and singular gemstones, before they ever reach the open market. A privilege reserved for those who invest at the source.
Fair prices, traceable provenance and independent certificates: every transaction rests on complete transparency, from the mine to your acquisition. You know exactly what you are buying, at what value and why — the foundation of a confident investment.
Our expertise is built on years of experience and an exceptional depth of knowledge. We select every stone with the utmost care to offer gemstones of superior quality and certified provenance. Contact us to explore our unique collections and benefit from our expertise.
Contact usTo invest in precious stones, you may purchase them and store them — in a bank vault, for instance — or turn to portfolio management through a dealer or wealth manager with genuine expertise in these tangible assets.
Each option carries its own advantages and drawbacks, but the first step in any long-term investment of this kind is always to understand how the precious stone market operates.
Choosing a dealer, a manager, or buying precious stones as an investment requires a clear grasp of what drives a stone's value, what risks are involved (such as fluctuations in demand or the presence of counterfeits), and when the right moments arise to resell — at auction, for example — or to release funds.
The market encompasses hundreds of types of stones, formerly known as "semi-precious stones", some of which buy and sell at prices far higher than diamond, emerald, ruby and sapphire — historically referred to as "precious stones".
Knowing the trends matters, as do the most stable options, which can depend in particular on provenance. Every gemstone has its own distinct character, and when looking to buy precious stones, comparing them carefully is essential.
A gemmological laboratory certificate is indispensable — sometimes two (GIA, LFG…). Diamond remains the classic safe-haven stone, yet diversifying one's holdings is strongly advisable: spinels, tourmalines, aquamarines and tsavorites all offer compelling alternatives.
The finest precious stones for investment are preferably unheated, faceted and, above all, untreated. The price of a precious stone depends on the criteria of clarity, colour, cut and carat weight, but also on its country of origin.
Certain varieties are rare and, when they are of excellent quality, they represent gemstones of great value. Notable examples include a Paraíba tourmaline, a Padparadscha sapphire, or a Mahenge spinel. When the provenance is highly regarded, these stones can appreciate considerably in value over the years.
It is possible to invest in precious stones while minimising risk. The best approach is to be guided by a reputable precious-stone dealer or gemmologist, as well as to understand the market. Certain stones tend to hold their value well, such as selected diamonds, Burmese rubies or Colombian emeralds.
Precious stones whose deposits are becoming exhausted tend to appreciate in value, as is the case with Ceylon sapphire, alexandrite or tanzanite. Demand is a key driver of a stone's value, which is not, however, directly affected by stock-market fluctuations, interest rates or inflation.
At Bonnot Paris, our global network allows us to fulfil any request, whether for traditional or rare stones.
Each stone is selected for its rarity, clarity and ethical sourcing, ensuring traceability, exceptional quality and fair pricing.

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 😋
