RARE blue swirl marble suspended on Sterling Silver box chain, along with Sterling Silver beads, rod and strands. This particular marble is warn down from it’s original size, which means it was tumbling in the sand for quite some time, a true treasure! 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!
