Here is an outstanding white metal pendant brutalist ring created by the collaborative project between two Danes, Jens Andersen and Erik Dennung ( see bio) in the 1970s, whch they called A+De Design.  Dennung died at the age of 82 in 2007, but his son Steen continued to run his business and shop in Copenhagen until 2016.  This ring, with a huge striped agate stone set in silver plate and held by huge bent nails, is possibly, together with the matching pendant (item 1873) and arm cuff (item 1872) a one-off  or bespoke set.
