Vintage 1960s Necklace, Extra Long Beaded, Faux Pearls, Shell or Mother of Pearl

Pretty vintage bead necklace circa 1960s or so. Larger beads of some sort of shell, perhaps mother of pearl or similar, with mini faux pearls in between. Has a total length of 52" long ( 26" doubled). No designer marks. Excellent near mint vintage condition. Nothing worth mentioning. Please note: These are vintage, preworn and/or preloved items. I do my best to list any issues, but signs of wear should be expected. Please feel free to contact me with any questions. I'm truly happy to help in any way possible and I'm always up for a chat.
