These adorable heart lock earrings are made of sterling silver (925) and feature the Tiffany & Co. hallmark. I purchased these previously, but I'm selling them now as I haven't worn them recently. Please check the photos for the condition, including any tarnish characteristic of silver. Please note that the original warranty card, box, and Tiffany & Co. bag were not included when I acquired them, so the earrings will be sold as is.

Thank you for looking.
