We were told by estate sale company that family went to Italy often and this necklace and chain are likely both from there. That seems to be the case based on the makers that are both Italian as best we can (the chain is even marked Italy). We needed a microscope to get the hallmark on the cross as it was so small. Chain is 18 inches long and Cross pendant is 1 inch long. The purple stones on the ends and in the middle are likely to be amethyst as that is commonly used. Total weight of cross and chain is 7.1 grams. Very nice and the purple jewels look nice when the light hits them. Will ship USPS with tracking to winning buyer
