What metals are used for gold-plated jewelry?

Gold-plated jewelry is typically made using a base metal such as brass, copper, stainless steel, or sterling silver. These metals provide strength and durability while keeping the cost low. Brass and copper are common choices but can cause skin discoloration if the gold plating wears off. Stainless steel is more resistant to corrosion, making it a popular choice for high-quality gold-plated jewelry.
