Tiffany & Co. does not sell wholesale jewelry and any said to be from a wholesaler is likely fake. The company also does not have an outlet store and does not place items on sale, as of 2015. All items are produced in the United States, Spain, Italy and Mexico.
To spot fake Tiffany & Co. jewelry, check the logo stamp. Genuine jewelry is stamped with the logo and its metal content on the chain as well as the pendant, if applicable. Also, the chain links on authentic jewelry are smoothly soldered and show no seams, rather than looking pressed together.
