About Gold Filled: The gold on 14k gold-filled jewellery lasts longer than gold plated. With 10x more gold. Composed of a solid layer of gold bonded with heat and pressure to a base metal, it has the look, feel and durability of 14K gold jewellery, and will not flake or peel. It's a beautiful alternative to solid gold and can be worn by most people with sensitive skin. Gold-filled is showerproof but it is recommended that you always keep your jewellery away from harsh chemicals such as perfume and lotions.
