You can wear your solid gold earrings all the time, as they are durable and resistant to tarnishing. However, we do not advise sleeping in any earrings, and you should still take care of them by cleaning them regularly to remove any dirt and oils that may build up on the surface. This is especially important for ear jewellery, as it can affect your ear health and hygiene. By doing this, you can keep your gold earrings shiny and beautiful for a long time.
