Durability of Gold Overlay and Gold Plated

Owing to different requirements in calculating acceptable thickness of the gold or gold alloy coatings, gold-plated and gold-overlay products vary in the ability to endure the passage of time. The thinness of gold-plating makes it vulnerable to deterioration, due to a susceptibility to friction, which can result in a gradual deterioration of the gold coating. While gold-overlay with a lower gold-to-metal content ratio may also show the signs of wear sooner than those with a higher ratio, manufacturer's labeling of these ratios allows consumers to more easily discern the comparative durability of the product. An overall comparison of durability in gold-plated and gold-overlay indicates added longevity for gold-overlay products, as compared to those designated as gold-plated.
