What Causes Gold Jewellery to Turn Black?

Have you ever noticed your gold jewellery turning black? The cause of this discolouration is relatively common and could be caused by several different things. In this blog post, we will discuss why gold jewellery turns black and how to prevent discolouration in the future.

There are two primary causes of gold jewellery turning black. The first is oxidation, which occurs when external agents such as air, water, and skin contact interact with the metal over time. This reaction causes a thin layer of tarnish on the gold’s surface, which appears dark. You may notice that some areas of your jewellery are more tarnished than others because those areas are more exposed to air and other elements.

The second common cause of discolouration is due to chemicals found in soaps, lotions, perfumes, and other beauty products. These chemicals can cause reactions with the gold alloy in your jewellery that result in it changing colour. To prevent this, removing your jewellery before getting ready or taking a shower is advisable to avoid any contact with these chemicals.

To keep your gold looking its best for extended periods, it’s essential to regularly clean it using a mild soap or cleaning solution specifically designed for precious metals. It’s also necessary to store your jewellery away from harsh elements such as direct sunlight or extreme temperatures; these can also lead to tarnishing faster than usual. Additionally, applying a protective coating such as rhodium plating can help protect against tarnishing and keep your pieces looking brand new for extended periods!
