1960s Robert Larin Brutalist Designer Pendant, Vintage Modernist Pendant

1960s Gold plated brutalist pendant by Robert Larin. It is a gorgeous example of free form brutalist design and quite unique as Robert Larin worked mostly in pewter and his gold plated pieces are quite rare.  The pendant itself is 1 5/8" long (not including the hang loop) and 1 1/8" wide. The accent stone is black and looks like glass.  It is fairly thick and chunky with textured sides on the pendant as well.  The matching chain is a little over 24" long. Pendant is in very good condition and is clearly signed as shown in the photos.
