Certification

A Promise of Authentic Craftsmanship

Every Jos Atelier creation is a reflection of traditional craftsmanship, artistic skill, and attention to detail. Each piece is handcrafted in Malta by Josianne Calleja, founder and master artisan of Jos Atelier.

Our jewellery is not mass-produced. Every design is carefully created, finished, and inspected to ensure it meets the standards of quality and authenticity that define the Jos Atelier name.

Certificate of Authenticity

Each handcrafted sterling silver piece is accompanied by a Certificate of Authenticity, confirming:

  • The piece has been handcrafted by Josianne Calleja of Jos Atelier.
  • The jewellery has been produced in Malta.
  • The item is crafted in genuine 925 Sterling Silver.
  • The piece bears the legally required hallmarks, including the Maker's Mark and the metal fineness mark where applicable.
  • The jewellery is an authentic Jos Atelier creation.

This certificate serves as a testament to the craftsmanship, quality, and provenance of your piece.

Hallmarking & Precious Metals

All sterling silver jewellery produced by Jos Atelier is created using genuine 925 Sterling Silver.

As required by law, pieces are hallmarked to verify the purity of the metal and the identity of the maker as . Hallmarking provides customers with confidence that the precious metal content meets recognised standards.

As handcrafted jewellery varies in size and design, hallmark placement may differ from piece to piece.

Filigree Certification

Filigree is one of Malta's most treasured jewellery-making traditions, requiring exceptional skill, patience, and precision.

Due to the specialised nature and cultural significance of filigree craftsmanship, all Jos Atelier filigree pieces are supplied with their own dedicated Filigree Certificate of Authenticity.

This additional certification confirms:

  • The piece has been handcrafted using traditional filigree techniques.
  • The intricate wirework has been individually formed and assembled by hand.
  • The design represents authentic artisan craftsmanship rather than machine production.
  • The piece is a genuine Jos Atelier filigree creation.

The Filigree Certificate accompanies the standard Jos Atelier Certificate of Authenticity and provides an additional record of the piece's craftsmanship and heritage.

Handmade, Not Manufactured

Small variations in texture, finish, and detail are a natural characteristic of handcrafted jewellery. These subtle differences are not imperfections but evidence of the artisan's hand and make every piece uniquely yours.

No two handcrafted creations are ever exactly alike.

Preserving Your Certificate

We recommend keeping your Certificate of Authenticity in a safe place for future reference.

The certificate may be useful for:

  • Personal records
  • Gift provenance
  • Collectability and heirloom purposes
