Does gold tarnish?

The pure gold does not tarnish. It’s the other metals used in gold alloy which do and so the lower the gold content in any alloy the more likely and the quicker the tarnishing process will occur. Gold of 18 carat is very resistant to tarnishing, but 14 carat and lesser carat gold tarnish slowly in air. The tarnish on gold items is not so obvious in their appearance because of their colour.

Can gold stain the skin or leave marks?

Pure gold will not mark the skin as it is chemically stable and it does not react with many substances. It is the other metals in gold alloy especially the lesser quality alloys which react chemically and may therefore mark the skin and also tarnish very quickly. Tarnish on gold jewellery is greatest on people who perspire and it shows as a dark smudge on their skin. This happens because perspiration contains sodium chloride and other salts and these interact with the high silver and copper content in low-alloy gold to form a dark salt deposit that, due to friction, appears on the skin, which is in contact with the metal. It can also appear where people on a certain type of medication. These people should avoid using jewellery with low-carat gold alloys.
