Antique Edwardian Shell Lady Cameo in Marcasite Ring c. 1910

This is a genuine antique cameo ring, carved out of Edwardian shell in a marcasite setting, with unknown stones as accents. When viewed under 10x magnification, you can see very light markings and indentations from carving tools on the shell. It was bought from an estate sale in Ontario and is used, but is in excellent condition considering its age. Truly a beauty.
