What is gold filled? Read more about it:
Gold-filled jewelry is made by bonding a thick layer of solid gold to a base metal core, usually brass. Unlike gold-plated jewelry, the gold layer in gold-filled pieces is much thicker, comprising at least 10% of the item’s total weight. This construction makes gold-filled jewelry durable and resistant to tarnishing, giving you the look and feel of solid gold without the high cost.
