Adjustable Chinese turquoise ring in sterling filigree (with minor flaw)

This is a lovely ring of the type crafted in China for export 50 or more years ago. It has recently been polished to do the silver full justice. There is a small chip and crack on one side of the turquoise cabochon as can be seen in the second photo, and I have reflected that in the price. I doubt it will get worse, but there is always the option of replacing the stone. . Adjustable, currently at about size 9. (d) Cross listed in Men's and Women's markets.
