Gold composite: A material that combines gold with other metals, typically silver and copper, to create a more affordable and durable alternative to pure gold. The key aspects of a gold composite are:

1. Gold content:

  • Must contain at least 5% (1/20) of real gold by weight.
  • Higher gold content generally leads to a more valuable and luxurious appearance.

2. Other metals:

  • Typically uses silver and copper for strength, affordability, and malleability.
  • The specific ratio of gold to other metals varies depending on the desired properties and regulations.
  • Some gold composites might include other metals like nickel, but this is less common due to potential allergy concerns.

3. Bonding process:

  • Different bonding techniques are used to attach the gold layer to the base metal.
  • Common methods include pressure bonding, roll bonding, and electroplating.
  • The quality of the bonding process affects the durability and longevity of the gold layer.


  • More affordable: Gold composites offer a more accessible way to enjoy the look and feel of gold without the high price tag of pure gold.
  • Durable: The presence of other metals makes gold composites more resistant to scratches and wear compared to pure gold.
  • Versatile: Available in various colors and finishes, offering diverse design options.


  • Not considered „real gold” by some standards due to the presence of other metals.
  • May not have the same investment value as pure gold.
  • Requires proper care to maintain its shine and longevity.
  • Examples:
  • Gold-filled: A common type of gold composite where a layer of gold is mechanically bonded to a base metal.
  • Rolled gold: Similar to gold-filled, but uses heat and pressure to bond the gold layer, often resulting in a thinner layer.
  • Vermeil: Gold plating over sterling silver, with a minimum gold content of 2.5 microns.
  • 14k gf®: A registered trademark and certification mark for gold-filled jewelry, findings, metal, and wire used by companies in the jewelry industry. 14k gf® ensures stricter quality standards and regulations, requiring at least 5% of 14 karat gold and only using gold, silver, and copper for composition.
