This beautiful pair of pierced earrings has been part of my own collection for some time now. They are fully hallmarked with European assay marks including 925 for sterling silver. The silver has not been polished and exhibits a deep time enhanced patina. I am not sure what the diamond shaped stones might be, possibly marble. They measure 1'' x 5/8''. Their original ear wires are in place but a little out of shape. I have worn them as is but you may want to replace them. Age appropriate wear.
