Two common methods exist for applying a layer of gold to a base metal. One involves mechanically bonding a substantial layer of gold to the base metal, while the other uses electroplating to deposit a very thin layer. The former results in a more durable and valuable product due to the significantly greater amount of gold utilized.
The longevity and overall value are directly impacted by the manufacturing process. Items constructed with a thicker layer of gold are inherently more resistant to wear and tarnish, extending their lifespan and maintaining their aesthetic appeal. Historically, these techniques have offered a more affordable alternative to solid gold, allowing broader access to gold jewelry and accessories.
