Precious stones with measuring instruments

Precious Stone Selection in Our Workshop

Precious stones are key elements in jewellery design. Their natural beauty, clarity and rarity make them unique and exceptional pieces. Diamonds, emeralds, rubies and sapphires are the most sought after. Semi-precious stones such as tanzanites, tourmalines, spinels and garnets offer a wide range of colours and shades, making it possible to create unique, personalised jewellery. The selection of gemstones is an essential stage in the creation of any piece.

Each precious stone is rigorously selected for its gemmological quality, including its clarity, refractive index and colour. Our gemstones come from certified suppliers, guaranteeing ethical traceability. The choice between natural or lab-grown diamonds, heated or unheated sapphires, or Paraíba tourmalines, is made according to the technical requirements of the piece you have in mind. Particular attention is paid to the cut, which affects brilliance and how the stone sits within a bespoke setting. This precise work allows us to create jewellery with exceptional stones, whose reflections and fire are unique, in our workshop close to Nantes.

Melting gold for the transformation of jewellery

Jewellery Workshop in Saint-Sébastien-sur-Loire

Creating a unique piece of jewellery using traditional techniques is the goldsmith's craft practised by your Nantes artisan jeweller. His skills are called upon at every stage, from design through to the setting of the stones. Jewellery has always been a popular fashion accessory, and the designs and styles on offer reflect the taste and personality of those who wear them. Yet few people know the true craftsmanship required to create and repair quality jewellery.

Setting is a crucial stage in the making of jewellery. Each precious stone is positioned by hand with extreme precision in its gold or platinum bezel, ensuring both security and beauty. The jeweller uses different techniques (bezel setting, claw setting or channel setting) depending on the style of the piece and the shape of the stone. This craft demands complete mastery of the tools and an excellent knowledge of materials. In our workshop in south Nantes, each jewel is conceived as a bespoke work of art, revealing the unique brilliance of every gemstone.

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.
