Gold Plated is made by bonding a thin layer of gold over affordable metals like silver. However, over time, the gold layer may fade due to the transfer of base metal molecules. The earrings are made with S925 stainless steel, so it’s very unlikely to irritate but if you have a sensitive ear, PLEASE DO NOT PURCHASE.
