I think the Brutalism of the 1970 was spurred by the space movies with their beautiful jewelry that the women wore. In Europe Bjorn Weckstom, from Lapponia, who made the jewelry for the movie and Jacob Hull,from Denmark, were two. I was surprised to see a Brutalist necklace (and a matching bracelet listed separately) to see these pieces from Ciner who made classsic jewelry. The necklace is 16" long and 1" at the widest. Marked Ciner (R) on the clasp and J Cooper on the back of the necklace. Excellent vintage condition.
