what is gold-filled jewelry?

Gold-Filled is at least 100 times stronger and more durable than plated jewelry and is the next best thing to solid gold. This is because the gold-filling process requires the use of solid gold, while plated jewelry uses a solution to give a gold coloring. This means, that with gold-filled jewelry, you get most of the benefits of solid gold like being water resistant, tarnish-resistant, and hypo-allergenic, but without that hefty price tag, or quick tarnishing plated items.
