Gold plated jewelry has a thin layer of gold applied to a base metal of copper or silver. The metals are then bound together by chemical or electroplating methods. Since rolled gold contains a higher percentage of gold, it has a greater resale value. Plated gold is certainly more affordable, but is more susceptible to damage and flaking, since the thin layer of gold can easily wear off. However, if you want longer lasting pieces of more value, consider rolled gold. As mentioned before, rolled gold can last for a very long time if taken good care off.
To clean rolled gold jewelry, simply use soap and water with a cloth or a soft bristled brush. When storing rolled gold jewelry, always place it in a separate pouch or box as it can get damaged if scratched by harder objects. Rolled gold is the perfect alternative to solid gold jewelry, offering a balance between price and beauty. Contents What is Rolled Gold? Rolled Gold vs. You may also like.
