An art collector seeks not only the beauty of a piece, but also the assurance that what they are acquiring is authentic. The certificate of authenticity for sculptures and works of art becomes the official document that guarantees originality, value, and trust. Without it, any sculpture can be considered an unsupported reproduction.
At Capa Esculturas, with decades of experience in artistic casting, we accompany artists and collectors through every stage of the process. Authenticity is certified by a document that supports the work and protects it against doubts or counterfeiting.
What is a certificate of authenticity for sculptures?
A certificate of authenticity in art is an official document that confirms that a work has been created by the artist or under their authorization. In the case of sculptures, this certificate is essential, whether we are talking about a unique sculpture or limited editions in bronze or steel.
This document includes essential information, such as:
- Name of the artist.
- Title of the work.
- Technique used and materials employed (bronze, stainless steel, marble, among others).
- Exact dimensions.
- Year of creation.
- Original signature of the artist or authorized representative.
- Serial number or edition number in the case of limited edition sculptures.
Unlike an invoice or contract, this certificate is the true “birth certificate” of a sculpture. For art lovers, it is the guarantee that allows them to buy with confidence and preserve the value of the work over time.
Importance of the certificate of authenticity in sculptures
The importance of certificates of authenticity in art lies in the fact that they protect both the creator and the buyer.
Artistic value of the sculpture
Certifying a work confirms that it belongs to the artist and removes any doubts about its originality. In the field of contemporary art, this proof is key to distinguishing between works and reproductions.
Economic value
The value of a certificate of authenticity for sculptures directly influences the sale price. A sculpture with a certificate can fetch a much higher price in art galleries or international auctions.
Historical and legal value
This document can be used as proof of authenticity for a sculpture in inheritance, insurance, or litigation cases. It also provides context about the piece’s history. For art collectors, having this backing is synonymous with legal certainty.
In short, the certificate of authenticity and value of a sculpture is the document that guarantees legitimacy, trust, and recognition in the art market.

What a valid certificate of authenticity should look like
Not all certificates are valid. An official document certifying the authenticity of a sculpture must meet very specific requirements:
Signature and verifiable information
It must be signed by the artist or an authorized representative and contain clear information about the materials, technique used, and date of creation.
Limited editions of sculptures
In the case of serial sculptures, the piece number and total number of copies must be indicated. A certificate of authenticity for a unique or limited edition work of art increases its exclusivity and collectible value.
Security features
Art foundries and high-quality galleries incorporate advanced measures such as seals, holograms, or special papers with Hahnemühle watermarks and fluorescent security fibers to prevent counterfeiting.
Whether it is a unique piece or part of a numbered series, a certificate of authenticity for bronze and steel sculptures confirms their originality and technical quality.
The role of art foundries
For many sculptures, the artist relies on a foundry to transfer the original model to final materials such as bronze or stainless steel. Here, the certificate of authenticity from the art foundry is essential. It guarantees that the work has been faithfully produced according to the original design and under the supervision of the creator.

At Capa Esculturas, we offer certificates of authenticity for artists, ensuring that each cast sculpture maintains its value and fidelity to the original design. Whether for unique sculptures or limited editions, our commitment to quality is based on offering works with a full guarantee of authenticity. This endorsement makes each piece an artistic heritage and reinforces its value in the art world.
Advice for collectors and buyers
Those who purchase sculptures should always request a certificate of authenticity for collectors that complies with all legal and artistic requirements.
Before finalizing the purchase, it is essential to request the document and check that it includes key information such as the technique used, the dimensions, and the date of creation. It is also essential to verify the signature and validity of the certificate, as this is what determines the reliability of the investment.
If in doubt, it is best to consult experts who can verify the certificate of authenticity of a sculpture and confirm that the piece is genuine. In this way, collectors can make a purchase with confidence and ensure that the work will retain its value in the art market.
The certificate of authenticity for sculptures and works of art is much more than just a piece of paper. It is proof of originality that guarantees value and allows art collectors to buy with confidence. Without this document, a sculpture loses much of its legitimacy in the market.
With each piece delivered, the Capa Esculturas certificate of authenticity becomes a guarantee for artists and collectors seeking security and high quality. Authenticity, value, and trust: three pillars that ensure each sculpture retains its essence and forms part of our artistic heritage.
