Vintage?? YSL Paris 1970s Hammered Disc with Rhinestones Collar Necklace (A8264B) Size: 16.25" Color: Gold, White Condition: Very good vintage Era: Circa 1970s Signed: YSL Details: This is signed twice, has the hang tag at the back, and the center disc is marked on the back. All the stones are faceted glass, bezel set. I believe this is from the 70s, as hammered jewelry was quite fashionable then. Strung on wire, metal tube beads, white pearlized beads are resin. Has a coppery gold textured link extension chain, 16.25". All plating is good. I could only find 2 up for sale currently at much higher prices Please look at all the photos, as they are part of the description. I try my best to point out any flaws.
