Gold-filled is a quality alternative to solid gold. This treatment, coming from the United States, consists of the application of a strong solid gold layer on a base metal with heat and pressure. Gold-filled is not to be confused with Gold Plated as there is 50 to 100 times more gold in a Gold-filled product than in a Gold Plated one (Gold-filled is legally required to contain 5% of solid gold by weight). Gold-filled is much more valuable and durable than gold-plated; it does not flake, fade nor change color. Anyone who can wear Gold can wear Gold-filled without any risk of allergy (even for earrings!). Gold-filled jewelry is an economical alternative to solid gold and is cleaned and maintained easily. At Zoaje, we use 14k rose Gold-filled that we import directly from the USA.
