Gold does not corrode. Despite this, gold ornaments start showing patches of other color after repeated use. Why?

Expert Answer:

Most ornaments that appear to be made of gold are actually made of other metal and only coated with gold. After repeated use, the gold layer tends to peel off in patches and the metal underneath, which is of a different color starts to show.
