How can you tell if something is Cartier?

To tell if something is Cartier, look for a maker's marking. Every Cartier piece, from jewelry to watches to sunglasses, bears the maker's marking in an inconspicuous area. These markings have changed over the years, so you can often use their style, placement and wording to date and identify your piece. Once you locate the mark, refer to trusted online resources to find out more about what that specific marking indicates. Find a selection of Cartier jewelry and accessories on 1stDibs.
