Gold filled is a popular material used in jewelry making that offers the look and feel of solid gold at a more affordable price. It is created by bonding a thick layer of 14k or 18k gold to a base metal, usually brass or copper. This process ensures that the gold layer remains intact and does not wear off easily, making gold filled jewelry highly durable and long-lasting. With proper care, gold filled jewelry can maintain its shine and beauty for many years. It is also hypoallergenic, making it suitable for those with sensitive skin.
