RARE Slag marble suspended on Sterling Silver box chain, along with Sterling Silver beads, rod and strands. This particular marble is one of the most interesting in my collection! It has incredible colors mixed in it, purple, brown, white and a hint of pink. Against the white back ground, it even looks like it has some blue in it. Check out all the pictures on this one, it’s quite amazing! Marbles became popular in the United States in the early 1900’s and vast popularity between 1915 and 1951, for children and adults alike. Collectors search for the swirls in the shapes of an S, 6 or 9, which date pre-1950. No matter the age of a marble, it’s a rare find on the shores of any lake or ocean! I have a very limited amount of marbles, so don’t miss out on this beauty!
