Checking the purity of the gold
We use a touchstone and specific acids to test the authenticity and purity of the metal (9, 14, 18 or 24 carat). This test does not damage your jewellery.
Appraisal of diamonds and precious stones
If your piece contains a diamond, an emerald, a ruby or any other gemstone, our jeweller carries out an analysis under the loupe and in the light, taking into account the quality, cut and brilliance of the stone.
Our offer for your gold
Once the appraisal is complete, we give you a clear, free quotation. If you accept, the purchase can be completed immediately, with prompt payment.

Frequently asked questions
Selling your gold in Nantes and Saint-Sébastien-sur-Loire
Which metals do you buy?
We buy your gold jewellery (18k/14k/9k), dental gold, coins and scrap gold (broken or odd pieces). In some cases, we can also take silver and platinum. If in doubt, simply bring your items in: we will check them on site.
Do I need to bring documents?
Yes. For any gold buying transaction, proof of identity is required (identity card, passport or driving licence). If you have an invoice, a certificate or a jewellery box, it can help, but it is not compulsory.
How is the price determined?
The amount is determined by the metal price, the weight and the purity (carats / thousandths). We carry out a purity test and weighing in front of you, with a transparent valuation that we explain to you.
Is payment immediate?
Once the offer is accepted, payment is made in accordance with current regulations, with secure payment and a written record. We give you a summary document of the transaction.
Can I sell a piece set with stones?
Yes. We assess any precious stones (diamond, sapphire, ruby and so on) separately where relevant. In some cases, an appraisal can increase the value beyond the weight of gold alone.
Do I need to make an appointment?
It is recommended, so that you are seen promptly. Book an appointment at the workshop near Nantes, in Saint-Sébastien-sur-Loire, for a free valuation with no obligation.

Beyond gold buying, we give precious metals a second life: the gold we buy is sent to an recycled gold supply chain, then reused to create new pieces in our workshop. This approach limits mining extraction and forms part of a commitment to ethical jewellery and the recycling of precious metals. To guarantee the quality and durability of our creations, we then work from a new alloy, carefully controlled and compliant with jewellery industry standards, while still honouring the value of the recycled gold within the process.
Do you have a project in mind? Gold buying in Nantes can become the starting point for a bespoke creation: the transformation of an old piece of jewellery, a new ring, wedding band, pendant… Book an appointment at the boutique for a free valuation, personal advice and a solution that is secure, local and responsible.

J’ai fait à nouveau appel aux services de Mr Maupas-Sehikyan, mais cette fois ci pour une création. Je suis venue avec une émeraude et deux bagues diamants de ma maman. Quand j’ai récupéré cette magnifique bague j’en ai eu les larmes aux yeux. Travail incontestable par un Mr très professionnel et de très bons conseils. Depuis je ne la quitte plus. Merci encore à vous Mr Maupas-Sehikyan et à très bientôt
Pour notre 25e anniversaire de mariage, mon épouse et moi-même avons réalisé notre rêve de renouveler nos vœux. Qui d’autres que le Joaillier Maupas-Sehikyan pouvait répondre avec tant de professionnalisme et d’humanité à nos envies quant à la confection de nos bijoux ? Pour nous qui avions déjà eu la chance de rencontrer cet orfèvre, la question ne se posait pas, car son travail n’a d’égal que celui des plus grands maîtres en la matière. Et le résultat est sans appel, nous sommes comblés. Un grand merci à lui.
Très satisfaite du travail de Monsieur Maupas-Sehikyan. Je recommande son travail très professionnel. Ma bague est particulièrement réussie. Elle est magnifique. Merci encore pour vos conseils.
Note de 5 étoiles sur 5.
Très satisfait du travail de Joaillier Maupas-Sehikyan ! Mon bijou est magnifique, réalisé avec soin et professionnalisme. Je recommande vivement
À quelques pas du centre-ville, la devanture ne paye pas de mine, le bijou est à l'intérieur ! Nous avons fait appel à Olivier Maupas-Sehikyan pou la création de bijoux avec l'apport de bijoux cassés et irréparables ou inutilisés comme ceux des bébés. Véritable joaillier, Olivier est passionné, force de proposition et avec une grande expertise technique. Il écoute notre histoire et nos souhaits pour créer le bijou qui nous ressemble, selon nos rêves, nos contraintes et notre budget. Je recommande à 200% !
