1970s Modernist textured goldtone bib necklace with hook clasp. Marked crown "TRIFARI." Overall measures: 6 inches long by 5 1/2 inches wide. Center: 1 7/16 inches long. Interior circumference is about 15 inches on the largest setting. Condition: Very good; minor wear to back. Possibly designed by Jonathan Bailey, but I haven't been able to confirm this attribution.
