18K gold filled or sterling silver chain link bracelet.
Gold Filled jewelry is made by permanently bonding many layers of gold sheets around a base metal (usually brass) using a heat and pressure process. Unlike gold plated jewelry, gold filled jewelry actually has a measurable amount of gold in it. This process makes for jewelry that does not tarnish, peel, chip or discolor.
Gold filled jewelry is 100% hypoallergenic, lead and nickel free.
