Gold filling is one of the most valuable and tarnish resistant processes for creating gold jewelry and other items. If properly cared for, your gold filled product can last a lifetime and thanks to its durability, there's no need to worry about wear.
Is gold-filled jewelry worth buying?
Gold-filled jewelry is a great economical alternative to solid gold. If taken care of, it can last as long as solid gold and won't tarnish or rub off. The downside is that if you were to resell your gold-filled jewelry, it would not have as much value as solid gold jewelry.
Which is better gold-filled or gold?
Unlike solid gold jewelry, gold-filled jewelry is composed of a solid layer of gold that is bonded to a base of another metal, such as sterling silver or copper. While gold-filled jewelry is typically less expensive than solid gold jewelry, it is actually more durable, looking shiny and new even with decades of wear.
