LEXICONDesign and market
Pièce unique
Also called: One-off, unique piece, one of a kind
An object made once and not repeated. The claim is only meaningful when repetition is actually prevented — either by the maker's undertaking, or by material that cannot be sourced twice.
Declared versus structural scarcity
A maker's promise not to repeat a design is a declaration. Scarcity enforced by material is a fact. When an object is built around a specific reclaimed component with its own wear pattern, a second version would require an identical donor part that does not exist. That distinction matters when assessing any claim of uniqueness, because the second kind cannot be quietly revoked when demand appears.
How it differs from limited edition and made to order
A limited edition is a fixed number of near-identical pieces, numbered and recorded, with the number stated before the first sale. Made to order means the piece is built after purchase from a design that can be built again — an honest category, but not an edition, and its resale behaves like that of a product. The three terms are used loosely across the trade and are worth asking about directly.
