Gold fill is superior to gold plate; gold filled materials have a much thicker layer of gold. Where gold comes off of a plated piece, Gold filled pieces can keep their layer for many years of constant use - even decades! Much like solid gold, gold filled jewelry will not cause an allergic reaction to skin sensitive to base metals. However, everyone's body chemistry is different, and there are those with high acidity that can cause gold filled materials to discolor skin. It is recommended that you do not wear gold filled jewelry while showering, doing dishes, or any other activity that could expose it to excess moisture or chemicals as this can possibly cause the ring to discolor the skin. This is not always a problem, and many customers have said they wear their rings 24/7 with no issues, but taking these precautions can keep your gold filled jewelry in it's best condition. Gold filled materials are also tarnish resistant. With that said, anywhere on a piece of gold filled jewelry that has had the core exposed or that has been soldered may tarnish due to the exposure of the core metal. Examples include the ends of earring posts, or the area that a ring or bangle is joined and soldered. This tarnish can be cleaned up with a soft toothbrush or non abrasive jewelry polishing cloth. Keeping this in mind, gold filled is an excellent way to affordably wear gold j
