You already know everything about the taxes that come with selling precious jewelry thanks to our article
Unlike watches, it is a little difficult to determine the value of a piece of jewelry, especially if you own a treasure without knowing it. You never really know who to turn to and going to your local jeweler seems a little complicated. Very often he will not buy jewelry and if he does, he will of course try to buy it from you at a low price so you will never truly know how much your jewelry is worth.
Did you know that most auction houses have their very own jewelry expert, who will be able to quickly provide an appraisal and offer to feature your piece in the catalog of their next sale if it matches house and sale standards? Either way, you will get an estimate for free with a short-term sales solution.

Jewelry often takes on a very special role. It is part of a person’s life, of a family, and it is often difficult to part with it. Whether it has been sitting in a safe for several years or has been worn until recently.
Therefore, an essential part of our expertise work consists in listening to our clients, their needs, their story and assisting them in the process. It is important to consider their priorities. It is not simply about putting a price on an object, it is about assigning value to a good that is dear to them, because selling a family jewel is generally done when carrying out a new project.
Our role is to be one of the key players in the transfer of this jewel, to write a new chapter in its story while getting the best results for the seller.
Once this has been taken into account, the actual expertise can begin. We first assess the general condition of the piece. We determine what metal it is made of, what gemstones, but also the jeweler’s work, we search for a signature or a possible hallmark. Finally, we give an accurate appraisal which reflects market reality as we know it and will make potential bidders want to join in to try and acquire the piece during the auction. The object’s intrinsic value can increase or vary depending on the origin without this being obviously quantifiable.
Of course, major French and international jewelry brands are at the top of the list, like Cartier, Van Cleef & Arpels, Boucheron, Lacloche, Mauboussin… and obviously two well-known designers, René Boivin and Suzanne Belperron, who have pride of place among our collectors.
For instance, I’m referring to an exceptional beauty box made of red enamel and diamonds from Lacloche Frères that we sold for a little over €130,000. Or a large Frédéric Boucheron brooch from 1888-1889 depicting a lilac flower (a special order and gift from Emperor Ferdinand of Bulgaria to Countess Anna de Grenaud de Saint Christophe for her wedding with Dimitri Strancioff, his prime minister) sold for more than €120,000. From Suzanne Belperron, a diamond and emerald jewelry set (circa 1935) which totaled around €236,000
In recent years, buyers and collectors have shown keen interest in antique jewelry dating from the 19th and early 20th centuries, the Art Deco era of course, as well as the 1940s and 1950s. Our collectors enjoy these pieces because they demonstrate the exceptional savoir-faire of the master goldsmiths and workshops of the time. French heritage and culture are highly represented in jewelry and still attract bidders from all over the world.
However, 80s jewelry has also been back in style recently and attracts growing interest from our buyers, especially when signed.
Quite simply, we are available every day. It is always easier to appraise a piece of jewelry physically, so we prefer to give our clients appointments at our study when possible.
Thanks to our representatives, we are also present in several French cities throughout the year, such as Lyon, Nantes or Reims, and outside our borders in Geneva, a hotspot for jewelry. Alongside this, we organize expertise days (more than a hundred per year) in major cities such as Bordeaux, Aix-en-Provence, Neuilly, Nice, Cannes, Brussels, Rome, Madrid, Strasbourg or Biarritz.

Here are a few examples:
My first favorite is an exceptional RENÉ BOIVIN necklace from 1935-1945 adorned with citrine and colored beryl, immediately recognizable with its sinuous lines and its unrivaled style. It is incredibly supple and perfectly hugs the curves of your neck – a real treat. It comes with matching ear clips and a pair of drop earrings set with an old-cut cushion diamond of around 4 carats each.

Once again, the harmonious colors and curves of this creation make it highly original. Need I remind you that Suzanne Belperron was Maison BOIVIN‘s designer for many years, and a great jewelry designer. A woman who created jewelry for women! This is reflected in her attention to detail and especially in the great comfort that comes with wearing these clip earrings.

I have been lucky enough to work for 10 years with a passionate expert,
We are committed to providing personalized and privileged service to our customers by taking the utmost care of their objects and works of art.
As I was saying earlier, we especially like old jewelry – Art Deco, 1940s-1950s, as well as any piece with a little bit of charm. Colored stones and diamonds. What is fascinating about this job is the constant discoveries we make, the people we meet, and the unknown world that opens up before us when the sale comes, until the final hammer blow, resulting from a collector’s desire to acquire an object.
First of all, it is important to note that auctions are public, meaning anyone can take part as a buyer, but also as a seller. Do not hesitate to walk into an auction house, we are here to help the client in the expertise process and advise him as best as possible by placing his object in the most appropriate sale.
At the end of the appraisal, we offer the seller the estimate that seems most in line with the market, while respecting his desire to get the best price. This is why we set a reserve price, which guarantees the seller a minimum selling price. We work in full confidence with our clients, we tell them we are on the same side and that our role is to support them to achieve the best result.
