Can gold tarnish or discolor?

Most metals experience some form of corrosion over time, but gold is an exception. In fact, gold will not corrode at all. This means that gold will not lose its shine or color when exposed to the elements. This unique property makes gold a popular metal for jewelry, making it one of the more valuable commodities in the world.

Are gold coins tarnished or not?

You will find that gold is often described as being tarnished, but this is not technically accurate. Even though gold is a noble metal, it will not tarnish in the way silver or copper do. If you see a gold coin that appears to have black spots on it, it is more likely that these are oxidation spots caused by storage in an improperly sealed container. While gold may not tarnish, it can become discolored if it is exposed to something acidic, such as vinegar or wine

Can gold tarnish or yellow?

The answer is yes, gold can tarnish and turn yellow, but it depends on the type of gold, the environment it’s in, and how it’s treated. In its natural state, pure gold is colorless, but it can turn a yellow color if it’s exposed to the air and other elements, such as sulfur and chlorine. If gold is alloyed with other metals, it can acquire a green or blue color.
