Artists employ meticulous methods to document and authenticate their stone sculptures, ensuring both provenance and long-term value. The process typically begins with detailed records, including high-resolution photographs from multiple angles, close-ups of unique textures or tool marks, and written descriptions of materials, dimensions, and techniques used. Many sculptors carve or engrave their signature directly into the stone, often in inconspicuous locations that don't compromise the artwork's aesthetics.

Contemporary artists frequently create certificates of authenticity that include specific details about the work, such as the quarry origin of the stone, creation date, and edition number for limited series. Some incorporate microscopic identification tags or RFID chips discreetly embedded within the sculpture. Digital documentation has become increasingly important, with artists maintaining cloud-based archives that track exhibition history, ownership transfers, and conservation records.

For particularly valuable pieces, artists may collaborate with professional authentication services that use advanced techniques like 3D scanning to create digital fingerprints of the sculpture. These methods help distinguish original works from reproductions and protect against forgery. The documentation process not only serves to authenticate the work but also preserves the artist's creative legacy for future generations of collectors and art historians.
