Gold fill jewelry offers (left diagram) excellent value for its price. It is water-resistant and tarnish-resistant, but careful treatment is necessary because it is not solid gold. Regular cleaning and periodic removal are recommended to maintain its luster. Gold fill jewelry features a base metal pressure bonded to a thick layer of solid gold, ensuring its tarnish resistance. Safe for individuals with metal allergies and it closely resembles solid gold without the hefty cost. Its permanent bonding and higher gold content make it superior in quality compared to gold-plated jewelry, albeit at a slightly higher price point. With proper care, gold fill jewelry can last a lifetime.

Gold vermeil (middle diagram) is a high-quality alternative to gold-plated jewelry, legally regulated to have sterling silver as its base metal and a specific gold thickness of 2.5 microns. It is more durable, valuable, and hypoallergenic compared to regular gold-plated jewelry. For an affordable way to achieve the look of solid gold, vermeil is an excellent choice. However, it requires careful treatment and should be kept away from liquids and moisture, and removed during swimming, bathing, or exercising.

Gold plated jewelry (right diagram) features a base metal, usually copper or brass, with a thin gold coating of at least 0.5 microns. It offers an affordable option but is of lower quality and durability compared to gold-filled and vermeil jewelry. Prone to tarnishing, careful attention is required regarding when to remove it and how to care for these pieces. Regular maintenance is crucial to avoid discoloration or green skin reactions, which can result from the base metal reacting to water. Periodic cleaning is necessary to maintain its appearance, and it must be kept away from all liquids and moisture, including during swimming, bathing, or exercising.
