When you want to wear a piece of jewelry only to discover that it has become discolored, it can seem a little annoying. Unfortunately, discoloration is a completely normal part of the aging process, regardless of the type of material your jewelry is made of.
- In the case of silver, reaction with the air leads to the formation of silver sulfide on the surface. This causes a change of color and creates the unsightly black areas that need to be cleaned.
- Gold jewelry can become tarnished by dirt, food, soap residue, makeup and sweat, which can cause it to lose its shine.
- Most costume jewelry consists of less expensive materials and, therefore, tends to tarnish even more rapidly. Before you start cleaning the jewelry, check whether any stains are purely superficial or if it has actually discolored due to tarnishing.
