What a find! This is a vintage ring that I swear is authentic Cartier! It is stamped with a serial number and 18k gold mark. It is missing the Cartier signature however. Whether this has been polished off at some point I am not sure, but because I cannot guarantee it to be authentic, it is priced only for the gold, diamonds and craftsmanship and not the Cartier name. You will see authenticated rings in this style for upwards for $3000 USD. 18k yellow, white and rose gold and 14 gorgeous diamonds. Cuff style ring sized to fit about a size 7.5-8. Amazing piece at a fraction of the original cost.
