It took a lot of searching around to find out exactly how old these are because they look brand new. Shiny, brilliant goldtone abstract shapes have unique clips that are "screwback adjustable" with patent still pending. The jewelry mark is not easy to see, and you may need loupe or heavy magnifier. Marked "Coro" in square, in script, and it is NOT easy to see the Pegasus! You can try enlarging he photos. I did my best to keep them clear. Flawless, possibly mint condition.
Will come in a gift box
