Found this at a recent estate sale. It had no clasp or way to connect it so we added a spring ring. There are no other marks we could find but it looks and feels like silver - likely a lower content than sterling. A scratch test revealed blue coloring (see last photo) indicating some positive silver content. Bracelet is not magnetic. The bottom line is this is definitely old, not a reproduction of any kind and we are hoping it?s timeless look makes it as desirable as we believe it is. Note a slight coloration difference between the new spring ring and the bracelet itself. We also added an extra ring on the opposite side to make it easier to wear. Bracelet is 7 inches long and one inch wide and weighs 27 grams. Will ship USPS with tracking to winning buyer. For a limited time we will offer free shipping with this item as well.
