Lot of Four Necklaces

This is a lot of four necklaces-two are exactly the same. # 1 is a necklace made of real or fake larger stone piece and small beads strung on two plastic cords. The problem is-the pieces have moved and will need to be repositioned or restrung. It measures 17.00 inches long. The stones appear to be actual stones with veining, and you can feel some of the imperfections in them. The smaller, round stones may be fake. # 20750 # 2 and # 4 This is a pair of fresh water pearl necklaces with purple beads and gold and silver metal beads. The necklaces are vintage, but I do not know how old they are or where they are from. Each necklace measures 19.00 inches long. The necklaces are vintage, and I cannot see how they are knotted. They are done in the exact same pattern. # 20754 # 3 This is a very shiny 20.00 inch long gold tone necklace with a red teardrop stone and white stones lining both edges of the chain. The hanging piece is 1 5/8 inches tall. # 20765
