This design reminds me of 1950's Silver Brooches with abstract cut-outs by Ed Weiner & Betty Cooke. My first impression was that it may have been designed to represent a crustacean or some type of bug (primitive biomorphic shape). Handcrafted modernist pin is slightly domed & out of round... tarnished front & back - I have not disturbed the Patina.
GREAT Looking Modernist Silver jewelry WEIGHS ~ 7.5 Grams, MEASURES ~ 1 1/2 Inches in Diameter & is unmarked. Retains Original FULLY Functional Safety Pin style clasp, pin stem & hinge. IMPORTANT Modernist Studio pin is in GOOD CONDITION! No Repairs or Excessive Wear - light scratches as would be expected from careful use... has not been polished in many years.
COOL "out of this world" unisex design pin would make a GREAT Addition to YOUR Mid Century Modernist, Designer Signed Silver jewelry ~ accessory collection!
