Karl-Ingemar Johansson was a trained silversmith active from the 1960s–1970s and worked closely with his partner, Cecilia Johansson. His work is typically defined by symmetrical structure, geometry, and clean, minimalist lines. He primarily worked in silver, making his gold pieces, such as this collectible 18-karat collar necklace, a rare find. Here, polished amethyst pendants take center stage, their facets creating pentagonal shapes that contrast with the dominant circles. A defining feature of the piece is its fully articulated construction: each pin element moves independently, allowing for multidirectional flexibility. This results in a dynamic composition that moves fluidly, enabling the necklace to conform naturally to the neckline. This articulation is achieved through precisely engineered hinge connections, reflecting a high degree of mechanical sophistication. The repeated pin-and-link configuration establishes a rhythmic, near-kinetic visual cadence.
