Tarnish is a thin layer of corrosion that forms over gold or sterling silver when outermost layer undergoes a chemical reaction when it reacts with the oxygen and sulphur in the air. It often appears as a dull, gray or black film or coating. The rate at which your jewellery will tarnish depends on the humidity of the air, the acidity of your skin, exposure to water and how you store your jewellery.

Pure gold is a very stable element, non-toxic and is even editable. Pure gold will never tarnish but it is too soft to be used in jewellery design. This means gold needs to be mixed with other metals which may cause it to tarnish. Gold is measured by it's purity, with 100 percent pure gold being 24 karat. The higher the percentage of gold the less likely is is to tarnish. Therefore gold jewelry that is 14k and higher may never tarnish. If it does, the process will be much slower than lower level karats.


All plated jewellery will wear off over time as layers of the plating are worn away to reveal the base metal. The speed in which it wears off depends on how you care for your jewellery, the acidity of your skin and how thick the plating is. Please read our jewellery care tips to prolong the life of your jewellery.

It is normal that gold and silver plated jewellery will tarnish and fade to reveal the original color of the base metal underneath. The speed in which plating wears off depends on how thick the plating is and how fast it tarnishes. The higher quality the plating the better protected is your jewellery.  At Annielka we only stock plated jewellery which is 2.5+ microns thick and for gold only 14k+ karats.
