What is gold-filled?
The core metal is sterling silver. A gold (or rose gold) alloy is then bonded with heat and pressure. Unlike plated (aka electroplated or "dipped") metals, Gold-filled is legally required to contain 5% or 1/20 gold by weight. (Gold plating is estimated to be 0.05% or less of the metal product. Gold plating will generally wear off rather quickly and will not stand up to heat, water or wear over time.) Gold-filled does not de-laminate or peel like plated or "dipped" products. Nor does it tarnish as readily as silver. Many owners find that they never have to clean gold-filled items at all. However, from time to time your jewelry may become dirty from everyday wear. To clean gold-filled it is best to use mild soap and water. Hot weather and water will not damage the material.
