Vintage Yellow Beaded 3-Strand Necklace, 47” Long, Layering Necklace, 1960-1970s

I have 3 necklaces like this, one in lemon yellow, one green & one blue. I will be listing the other 2 after I finish listing this yellow one. This is from an estate that had a ton of vintage necklaces, all were about the 1960s-1970s era. I know it’s hard to place a timeframe on a beaded necklace like this, but I truly believe this one is from that time period. Measures 47” from end to end. 3-strands of yellow beads of varied sizes. Spring-ring closure. A great vintage accessory! Thanks for taking a look!
