Invest with complete confidence. We provide comprehensive support and security for every investor:
Each stone is accompanied by a certificate issued by a recognised independent laboratory (LGL, GRS, ICA, Bellerophon…), attesting to its origin, treatment and characteristics. An essential document to the value of an asset, it guarantees the traceability of your stone and facilitates both its resale and its transmission.
From stone selection through to the finishing touches, our jeweller-dealers guide you at every stage. You benefit from personalised expert advice to make the right choices and bring to life, with complete peace of mind, a creation conceived especially for you.
Authenticity lies at the heart of our approach, from the ethical provenance of our stones — sourced directly, with no intermediaries — to the transparency of our pricing and our relationships. Every stone is natural and certified, with no undisclosed treatments.
At Bonnot Paris, we combine decades of jewellery expertise with a commitment to sourcing the finest and most exclusive gemstones. Each piece is meticulously crafted in our French atelier, ensuring that you invest not only in a gemstone but in a work of art.

Thanks to our direct presence in Sri Lanka, Bangkok and Jaipur, you gain first-hand access to rare and unique gemstones, before they even reach the 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 exceptional savoir-faire. We select every stone with the utmost care to offer superior-quality gemstones with certified provenance. Contact us to explore our unique collections and benefit from our expertise.
Contact usTo invest in precious stones, you can purchase them and store them in a bank vault, or turn to portfolio management through a dealer or wealth manager with expertise in these tangible assets.
Each option has its advantages and disadvantages, but the first step in this long-term investment is always to understand how the precious stone market works.
Choosing a dealer or manager, or buying precious stones as an investment, requires identifying what influences the value of stones, what the risks are (such as fluctuations in demand, counterfeits…), and what the best moments are for resale — at auction, for instance — or for withdrawing funds.
The market comprises 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".
It is important to know the trends, as well as the most stable options, the latter depending in particular on provenance. But every gemstone has unique characteristics, and when looking to buy precious stones, one must compare them carefully.
A gemmological laboratory certificate is essential — sometimes two (GIA, LFG…). The safe-haven stone is the diamond, but it is absolutely vital to diversify this asset class, for example with spinels, tourmalines, aquamarines or tsavorites.
Precious stones for investment are preferably unheated, cut and strictly 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 of excellent quality, are gemstones of great value. For example: a Paraíba tourmaline, a Padparadscha sapphire, a Mahenge spinel. If the provenance is renowned, they can appreciate greatly 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 renowned precious-stone dealer or gemmologist, in addition to having a sound knowledge of the market. Certain stones tend to hold their value, such as some diamonds, Burmese rubies and Colombian emeralds.
Precious stones whose deposits are becoming exhausted gain in value, as is the case with Ceylon sapphire, alexandrite and tanzanite. Demand is a key factor in a stone's value, which is nonetheless not directly affected by stock-market fluctuations, interest rates or inflation.
At Bonnot Paris, our global network enables us to fulfil any request for both traditional and rare stones.
Each stone is selected for its rarity, clarity and ethical sourcing, guaranteeing traceability, exceptional quality and fair prices.

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 😋
