ONYROS · AUTHENTICITY

Authentic.
Traceable.
Unique.

Every artwork carries its own story, signature and distinct identity. That is why each one is documented, registered and accompanied by verifiable information.

A GUARANTEE THAT LASTS

Authenticity should be more than a claim.

An artwork gains value through its documented history as well.

Every Onyros original and Fine Art edition is identified through precise details: title, year, technique, medium, dimensions and edition number, where applicable.

This information remains with the artwork over time, making it possible to identify and verify it while preserving a clear record of its provenance.

THREE CERTAINTIES

Every artwork leaves a trace.

Signature, documentation and registration remain with the artwork over time. They do not replace the work itself: they preserve its identity, provenance and history.

Certificate of authenticity for an Onyros artwork

THE CERTIFICATE

The document that stays with the artwork.

The certificate is more than a decorative document. It brings together the information that identifies the artwork and confirms its connection to the Onyros Archive.

Each certificate bears the same unique code as the numbered hologram applied to the back of the original artwork or Fine Art edition.

01

Artwork details

Title, year, technique, medium and dimensions.

02

Signature and code

The elements that link the certificate to its corresponding artwork.

03

Archive verification

The ability to verify the artwork against its official archive record.

VERIFICATION AND TRACEABILITY

Every detail can be verified.

Certificate, artwork and the Onyros Archive are linked by precise identifying elements. The system applies to both original artworks and Fine Art editions.

Instant verification

The QR Code printed on the certificate provides direct access to the artwork's record in the Onyros Archive, where its details and registration can be verified.

02 · HOLOGRAM
H

A unique code

A numbered hologram is applied to the back of every original artwork and Fine Art edition. The same code appears on its certificate.

03 · ARCHIVE
A

A permanent record

The code links the artwork to its official record, preserving the connection between the work, its certificate and its provenance over time.

ORIGINALS AND FINE ART EDITIONS

Two forms. Two distinct identities.

An original and an edition are not the same. Each follows clear, transparent and recognizable standards.

01 · UNIQUE ARTWORK

The original

The unrepeatable presence of gesture, texture and every creative decision that transformed the image into a one-of-a-kind artwork.

  • One unique piece
  • Original signature
  • Dedicated certificate
  • Archive registration
02 · LIMITED EDITION

The Fine Art edition

A limited, numbered and signed edition, produced using carefully selected materials to preserve color, detail and character over time.

  • Declared edition size
  • Individual edition number
  • Artist’s signature
  • Medium and dimensions specified

A PERSONAL TOUCH

A signature. A dedication. A personal gesture.

Before delivery, I personally sign every artwork and, when requested, add a short dedication on the back or on the certificate. A small gesture for a special gift, or simply to make the artwork even more personal.
