This is another antique piece I purchased from a woman who had jewelry dated 1929. As you can see from the box this is also old. The chain is marked on both ends. The F has 3 diamond chips. As with her 1929 ring it was well maintained and barely. She had a beautiful collection...I already sold 2 of the dated pieces. Here is a change to own a piece of history. I will bundle shipping and give 10% discount if both are purchased. Chain is 17 inches the F is a half inch.
