How long does 18k gold plated jewellery last?

The lifespan of 18k gold plated jewellery depends on various factors such as the quality of the plating, the thickness of the plating, and how well it is cared for. In general, 18k gold plated jewellery can last for several months to a few years, but it will eventually start to wear off, revealing the base metal underneath. The rate at which the plating wears off will depend on factors such as the thickness of the plating, how often the jewellery is worn, and how well it is cared for.

If the plating is thick enough and the jewellery is well maintained, it can last for a longer time. Proper care and maintenance such as regular cleaning, avoiding exposing it to harsh chemicals, and removing it during activities that can cause damage can help prolong the life of the 18k gold plated jewellery. It's worth noting that gold plated jewellery is not a long-lasting option as compare to solid gold jewellery and may require frequent re-plating to maintain it's appearance.
