Turn your gold into a contemporary piece of jewellery

Do you own a family ring, a broken chain, odd earrings or jewellery you no longer wear? At Maupas Sehikyan, we offer a solution that is elegant, responsible and full of meaning: using the gold you supply to create a modern piece of jewellery that reflects your style.

Your gold, your story… a fresh start

Rather than leaving these pieces forgotten in a drawer, we can recover the metal and recycle it to craft a creation in keeping with today's tastes:

  • a slimmer, more contemporary ring,

  • a minimalist wedding band,

  • a contemporary pendant,

  • a reimagined engagement ring with a stone brought back to its full glory.

How does it work?

  1. Assessment of your jewellery: we examine the type of gold, its condition, its weight and the feasibility of the project.

  2. Bespoke design: sketches and advice on style (yellow, white or rose gold, matt or polished finishes, setting).

  3. Recycling and making: your gold is melted down, then worked to achieve an impeccable result, using alloys suited to the strength of the piece.

  4. Jeweller's finishing touches: fitting, polishing, resizing and quality control.

Why choose gold supplied by the client?

  • A responsible approach: you reuse a material that already exists.
  • Sentimental value: you keep the story while changing the style.
  • A unique piece: a bespoke creation you will find nowhere else.
  • An optimised budget: you reduce the cost of materials (depending on weight and project).

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.

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% !
Signet ring with heraldic engraving in 18-carat yellow gold, bespoke engraving

Heraldic Engraving And Coats Of Arms

In our jewellery workshop, we are proud to offer a specialist heraldic engraving service. Each signet ring is meticulously engraved to faithfully depict the coat of arms you wish to immortalise. Crest engraving is an ancient art, symbolising family heritage and tradition. With our expertise, we engrave every detail with precision, creating a unique piece of jewellery that transcends generations.

Heraldic engraving is an ancient art that allows you to personalise a piece of jewellery with family coats of arms, blazons or symbols of identity. At Maupas Sehikyan Joaillier, we create bespoke engravings in our workshop in Saint-Sébastien-sur-Loire, in keeping with the rules of traditional heraldry.

Every coat of arms engraving is executed with exceptional precision, whether on an 18-carat gold signet ring, a platinum ring or a personalised pendant. Thanks to our expertise in hand engraving and high-precision laser engraving, we deliver a result that is crisp, lasting and faithful to your expectations.

Our creations bring out the best in intricate blazons, noble symbols, historic escutcheons and stylised monograms. Every detail is studied, from the helm to the supporters, by way of the motto and the tinctures. We work with you to interpret your coat of arms or to design one from your family genealogy.

Choosing a heraldic engraving on a piece of jewellery is a way of affirming a history, a lineage or a cultural heritage. It is also a unique and symbolic gift, often handed down from generation to generation.

Whether you are passionate about heraldry or antique jewellery, or simply looking for a personalised piece of jewellery, our workshop will guide you with rigour and passion. Entrust us with your project: signet ring, ring, wedding band or medal, we will create it with respect for tradition and artisan excellence.
