Very good pre-owned condition. Some fine surface scratches, patina. We only lightly cleaned the pendant to preserve the patina.  

One of the circles is marked 830S and FINLAND on the outer side.  Pendant is unsigned but attributed to Jorma Laine, a renowned Nordic modernist silver smith.  He designed this pendant for Kultateollisuus Ky, one of Finland's oldest jewelry designers.

Pendant is strung on a vintage sterling silver rolo chain marked STERLING on the spring ring clasp. Chain is not Jorma Laine nor Kultateollisuus.

An extraordinary mid century industrial design, comprised of articulating chain maille-style segments. 

Carefully packaged and shipped in a jewelry box.
