Catalogue Raisonné

The Catalogue Raisonné of Cruz-Diez is a thorough index of his works of art containing detailed information such as the title, size, date of production, condition, provenance and pictures of each individual piece. Completion of the Catalogue Raisonné of Cruz-Diez is an on-going priority of the Cruz-Diez Art Foundation.


A catalogue raisonné is used to retrace the history of an artist’s work. Cruz-Diez has always been very methodical and organized in his approach. His extensive archive of blueprints, maps and original plans enables us to identify genuine pieces.

If you are in possession of a Cruz-Diez artwork and would like to have it verified by the Cruz-Diez Art Foundation we would appreciate you completing our verification form and providing high-quality images in order to nourish our catalogue. Please help us retrace history by telling your friends or institution with a Cruz-Diez piece to contact us.


The Cruz-Diez Art Foundation will not share your private information with third parties unless you authorize us to and will treat your personal details in the strictest of confidence.


Cruz-Diez has given authorization to the Cruz-Diez Art Foundation, in collaboration with the Cruz-Diez workshops, to deliver certificates dictated by the certification committee confirming exclusive authorship of works created by the artist.

The Cruz-Diez Art Foundation refer to Cruz-Diez’s archives, where all blueprints and original plans are kept, prior to making a decision. This enables the certificates committee to identify genuine pieces. A fee is payable to cover the cost of investigation, from which will come the possibility of obtaining a certificate. If a piece is deemed authentic the certificates committee will then issue a certificate of authenticity. Each certificate is unique and copies are not allowed.

If you own a Cruz-Diez artwork and would like to purchase a certificate, please download and complete our application form. You should also refer to the General Conditions for the Authentication.



The preservation and restoration of Cruz-Diez’s works is important to him. Rather than following the rule that it is the artist’s hand on the canvas that must be preserved, for Cruz-Diez, as it was for his contemporaries, it is important that the result is maintained. Cruz-Diez achieves his result through the use of repeated modules that must be identical, therefore these modules must be preserved.


In the 1960s artists were experimenting with new ways of creating paintings, breaking the boundaries between 2D and 3D by making volume using new materials rather than oil or gouache. The use of materials such as acrylic, metal, wood, silkscreen, PVC and mechanical workings means that some of the artworks produced have not aged well. This is why Cruz-Diez has kept meticulous archives detailing exactly how the artworks must look upon completion.


All of the plans and materials needed for restoration can be found in Cruz-Diez’s workshops. This ensures their preservation as the artist intended. Where previously used materials have been surpassed by modern equivalents, Cruz-Diez’s workshops are best placed to make these alterations, under the instruction of Cruz-Diez himself. The result is always identical in appearance to that of the original.


These same principles apply to Cruz-Diez’s architectural structures. Although Cruz-Diez always tries to find the best materials that will last, inevitable color fading and material erosion due to external elements means that these too must be restored. The Cruz-Diez Art Foundation advises owners of a Cruz-Diez artwork to exercise responsible care and contact us directly with regards to maintenance requests.


This new concept of restoration for contemporary art came to the attention of The Ecole du Louvre, who visited the Cruz-Diez atelier in Paris to understand how it works.
