Something similar happens with other metals also.
Example-:1.Magnesium ribbon is dull when exposed to air and shiny if we cut it.
2.Silver objects and jewellery becomes black.
3.Copper statues and vessels become dull green.
reason-:all these metals react with components in air.But,the gold jewellery does not become dull.
