What is gold filled jewellery?

Definition
Gold filled jewellery is made by pressure-bonding a layer of solid gold to a base metal core under heat, creating a durable gold surface that is far thicker than electroplated gold. By definition, the gold layer must constitute at least one twentieth of the total weight of the piece, and the carat of the gold must be at least 10kt, though 14ct gold filled is most common. Rolled gold is an older term for the same process. With proper care, gold filled pieces can last for decades and are a great deal more resilient than gold plated alternatives.
Frequently asked questions
- Is gold filled real gold?
- Yes, gold filled contains a genuine layer of solid gold that is bonded to the surface. It is real gold, just over a base metal core rather than all the way through. The gold layer is significantly thicker than in plated jewellery.
- What is the difference between gold filled and gold plated?
- Gold filled has a thick layer of gold mechanically bonded to the base metal, representing at least 1/20th of the total weight. Gold plated has a much thinner electrochemical coating, often less than 0.5 microns, which wears off faster.
- How do you care for gold filled jewellery?
- Treat it similarly to solid gold: keep it away from chemicals and perfume, dry it thoroughly after contact with water, and store it separately to avoid scratches. With this care, gold filled pieces can look good for many years.
