Gold Filled jewelry is created by layering gold on the surface of jeweler’s brass and bonding with extreme heat and pressure. The gold alloy makes up 5% of the total product weight-100% more gold than gold plated pieces. Gold filled is much more affordable than solid gold, but with the same durable color and shine. It is much more durable than plated metals because the gold content is significantly thicker. With proper care to not scratch the surface and cleaning with soap and water, your piece will be in great shape for years!
