This Y-style necklace has a length of 15" + 2.5" drop, as well as a 3" extender. I'm unsure of the materials, probably silver plated orbs set with crystals, and faux pearls. However, it's very pretty and in great condition for an older piece. Earrings included finish the set, with fish-hook earwires. As with any vintage costume jewelry, please be aware there can be patina and imperfections of plating, as well as wear on portions of the piece. I try to bring anything out of the ordinary to your attention when I can. But reviewing the pictures and asking questions ahead is the best way to be aware before purchasing. All sales final. Thank you for shopping my closet!
