Gold filled jewellery is an economical alternative to solid Gold!
Gold filled is an actual layer of gold pressure-bonded to another metal such as silver or brass. Gold filled is not to be confused gold plating as gold filled literally has 100% more gold than gold plating.
Gold filled is much more valuable and is tarnish resistant. It will not flake off, rub off or change colour. As a matter of fact, anyone who can wear gold can wear gold filled without the worry of getting an allergic reaction from the jewellery.
