Gold-Filled Jewelry is made with solid 14 Karat gold tubing filled with brass. The gold tubing makes up 5% of the total jewelry weight. This is known as 14/20 gold-fill. Gold-filled jewelry has the same look and feel of solid 14 karat gold. Unlike gold plated jewelry, gold-filled jewelry will not flake, peel or wear off. With proper care, your gold-filled jewelry will last a lifetime.
