Gold comes in several forms in jewelry. Gold-filled refers to metal, usually brass, to which gold has been mechanically bonded and is measured in terms of the proportion of gold to other metals and the karatage of the gold. Gold-plate refers to metal to which gold has been applied by various means. Electroplating is the transference of gold to the surface of other metals by electrical action. Plated gold is generally thinner and less durable than filled gold.
Silver also comes in several forms in jewelry.
