A 70’s Modernist Gold Brooch by Swiss Firm Gubelin. The 18k gold 2 1/8″ x 1 5/8″ organic shaped brooch in a gold mirror finish with a textured matt gold “crevice”. The two-textured gold combination of the matt and shiny surface makes this piece an easy go-to for all kinds of jewelry companions. Gubelin, renowned for their watchmaking was a forerunner of modernist jewellery design in the 1960s and 1970s. This piece, dubbed the Grand Canyon collection, came in the form of a necklace, brooch, ring, and earrings. Chic and Sculptural.
