Here is a high-end Vintage Rhinestone Bib Collar Necklace from the 1960's era. It is unsigned, but I believe it is Delizza & Elster, Juliana or another high-end brand and has many of those attributes. This glitzy piece features prong set smoke, gray and aurora borealis rhinestones set in shiny gold finish. Quality stones, claw-like prongs, dog tooth crimped cups, and quality plating. In great vintage condition. Sparkly! No missing or darkened stones. No finish wear to gold or foil wear. I do not see any bad scratches or chips. Very minimal wear. Measures: 16" long x 1-1/8" at the widest point. Simple hook clasp.
Thanks for looking!
