Vintage Yves Saint Laurent Crystal Bead and Rhinestone Rondelle Necklace

Gorgeous vintage Yves Saint Laurent necklace comprised of cut crystal beads that catch and refract light beautifully, black iridescent beads (they have the appearance of hematite, but I’m not sure what they’re made of - possibly glass), rhinestone rondelles, and white glass beads on wire links, with a signed YSL s-hook style clasp, and chased metal loop. It’s about 32 inches in length. See photos for details.
