Gold filled jewelry is a type of jewelry that has a solid layer of gold mechanically bonded to the surface of a base metal. This process results in a piece of jewelry that has the look and feel of solid gold but is more affordable and less likely to cause skin irritation compared to solid gold.
The gold layer on gold filled jewelry must be at least 5% of the total weight of the piece, and it is typically much thicker than gold plating. Because of this, gold filled jewelry can last for many years with proper care and maintenance.
Gold filled jewelry is often used for making chains, bracelets, earrings, and other jewelry items. It is a popular alternative to solid gold for people who want the look of gold without the high price tag, and it is also an option for those with skin sensitivities to other metals.
It's important to note that gold filled jewelry is not the same as gold plated jewelry, which has a much thinner layer of gold and is more prone to wear and tarnishing over time.
