In the porcelain sculpture market, certificates of authenticity (COAs) serve as indispensable tools that bridge the gap between artists, collectors, and dealers. These documents verify the provenance, authorship, and legitimacy of a piece, directly influencing its market value and desirability.

For collectors, COAs provide peace of mind, confirming that their investment is genuine and not a reproduction or forgery. This is especially critical in high-value transactions, where even minor doubts about authenticity can significantly diminish a piece's worth. The certificate often includes details like the artist's signature, creation date, and materials used, creating a transparent chain of ownership.

Artists and galleries also benefit from issuing COAs, as they establish credibility and protect their reputation. A well-documented piece commands higher prices and attracts serious buyers, fostering long-term trust in the market. Furthermore, COAs help combat fraud, which remains a persistent challenge in the art world.

As the porcelain sculpture market grows, the demand for standardized, tamper-proof authentication methods increases. Digital certificates and blockchain technology are emerging as modern solutions, but traditional paper COAs still dominate. Ultimately, these certificates don't just validate art—they sustain the entire ecosystem of buying, selling, and preserving ceramic masterpieces.
