Gold filled jewellery, also known as rolled gold or gold overlay jewellery, is a type of jewellery that consists of a layer of gold bonded to a base metal, such as brass or copper. The thickness of the gold layer varies depending on the quality of the piece, but it must be at least 5% of the total weight of the item.
Unlike gold-plated jewellery, which uses a thin layer of gold that can wear off over time, gold filled jewellery is much more durable and long-lasting. The thicker layer of gold ensures that the piece will not tarnish or flake off, and can last for many years with proper care.
Gold filled jewellery can come in a variety of styles and designs, from simple chains and earrings to more elaborate pieces set with gemstones or pearls. It is also available in different gold colors, including yellow, white, and rose gold.

When purchasing gold filled jewellery, it is important to look for reputable retailers who use high-quality materials and craftsmanship. It is also recommended to avoid exposing the pieces to harsh chemicals or abrasive materials, as this can damage the gold layer.
Overall, gold filled jewellery offers a beautiful and affordable alternative to solid gold pieces, with the added benefit of durability and longevity.
