Vintage Natural Stone Ivory Silvertone 28" Chain 1.75" Gemstone Pendant Necklace

Vintage Natural Stone Ivory Silvertone 28" Chain 1.75" Gemstone Pendant Necklace All of the vintage Cabochon and stone jewelry items in my store were given to me by a friend and were part of her mother's collection from the 70s-90s so they are vintage, but I do not know the origin. Most are unmarked (this one is marked JAPAN on the clasp). I also can't verify the metal content, but they all have varying degrees of magnetism. Chain measures 28" (56" full circumference) and the pendant is 1.75" long by 1" wide. The bust is smaller than an average person so it will look bigger on the bust than they will on you. There is little to no signs of tarnish or patina. Condition: Excellent pre-owned condition. There is an inclusion on the stone that is part of the natural imperfection. Please see all photos for details.
