Yves Saint Laurent Pins & brooches Golden

large brooch with pearly white cabochon on worked gilded metal frame.
signature at the back.
Can be worn as a brooch or pendant (thanks to a hook)
5cm x 5 cm
very good condition, however, note a few tiny marks on the cabochon, see the 2 latest photos (very difficult to highlight the flaws because they are really imperceptible).
The earrings matching the brooch / pendant are available in my shop (see last photo)
