Gold may be a little red because it is prevented from being in a sulfur-containing environment for too long or from being in contact with acids. When gold is red, it can be solved by heating and burning.

There are many ways to express the content of gold, such as pure gold, pure gold and 24K gold, but there is no pure gold. This is because impurity elements are inevitably added when extracting gold, which also leads to the discoloration of gold.

Matters needing attention in gold maintenance

It is normal that gold jewelry gradually loses its luster due to sweat and other factors. In this case, the customer needs to return the jewelry to the jewelry store for cleaning.

Don't store gold ornaments and silver ornaments together, so as not to collide with each other and make the surface of gold ornaments turn silver. When the gold ring and platinum ring are worn together, it is easy for them to rub against each other, which makes the surface of the gold ring locally white and platinum.
