Gold Filled jewellery contains a solid layer of gold 5 to 10 times thicker than gold plated jewellery. It is heat bonded to a base metal, such as brass or copper in our collections. Gold Filled jewellery is more precious due to its higher gold content! A gold filled piece contains 5% of solid gold.  It is perfect for sensitive skin due to its durable, high gold composition and tarnish resistant nature.
