A beautifully crafted 14K yellow gold filled 3.2mm mariner link chain. The chain secures with a durable lobster clasp. The chain measures 20 inches in length. Gold filled jewelry consists of a layer of gold bonded to the underlying base metal. Unlike gold plating, gold filled jewelry is crafted with gold that constitutes at least 5% of the total item weight and will not fade or tarnish like plated jewelry often can. It can withstand heat and water over time.
