Wrap jewelry - we now call it memory wire - first made an appearance in the early 1950's. This circle of large imitation pearls is about 12.5" with an extender to about 16" - best for a smaller neck size, as it should appear to float above your collarbone. The wire is not stiff, so it feels comfortable, not tight when worn.
The pearls may appear gray or silver on some monitors - they are white.
I see no defects and no signs of wear. A fun 50's piece that will instantly dress up any outfit!
