The Door-Knocker series features unique and pure design details. The series is influenced by travels through some of Europe's greatest cities and their rich history. The doors in these cities have distinct elaborate door knockers that fuse function and design and are in their own way, beautiful works of art.

The Necklace features a thin cable chain, with a moving door-knocker ring spaced in the middle of the chain, and a lobster clasp closer. Inscribed with the Linn Lømo monogram for authenticity.
