Most gold does not have this problem. However, if gold is left in the air or exposed to various chemicals it can turn red. This is because the gold can form a thin layer of oxide on its surface. While it may not be visible to the naked eye, this does not diminish the value of the gold.
What will happen to gold if I leave in red?
In general, gold does not tarnish red. However, gold will still lose some of its luster as time goes on. This is because gold can pull oxygen from the air and form a kind of protective coating on the surface. If not periodically cleaned and polished, this oxidation will slowly reduce the pure gold color of the metal.
Can gold tarnish red jewelry?
If you wear your gold jewelry frequently, it can lose its shiny appearance. For example, if you wear a choker, necklace, ring, or earring every day, it will look dull after a few months. The gold will develop a dull metallic color known as gold tarnish. You can prevent gold from tarnishing by regularly cleaning it with a soft cloth. Try rubbing the jewelry with a mixture of baking soda and water. This will remove any dirt and leave the gold looking shiny again.
