First of all, I have to say that 18K gold is not that dark yellow! In fact, it appears charming white or red because it contains other metals. But if it is not properly maintained, it may fade. Generally, it is six months to 1 year. So, next I will teach you some maintenance tips!
First of all, it is necessary to avoid 18K gold from contacting with chemicals, such as perfume and cosmetics. These substances may corrode the gold ornaments and make the baby lose its luster.
Secondly, we should reduce friction and collision. Although the gold ornaments are hard, they can't stand the toss. Therefore, care should be taken during wearing to prevent scratching or impact.
Finally, remember to clean and maintain regularly. Gently wipe the surface of the gold ornament with a soft cloth to keep it clean and shiny. If conditions permit, you can also send the gold ornaments to a professional jewelry store for cleaning and maintenance.
