If you're a jewellery lover, you've probably noticed that over time, your beloved pieces can start to lose their shine and develop a dull, discoloured appearance. This is a natural process called oxidation, and it's something that all metal jewellery experiences to some degree. But why does it happen, and what can you do to prevent it?
At Melchior Jewellery, we're passionate about helping our customers keep their jewellery looking its best. That's why we're excited to share our insights on the science behind oxidation and some tips to help you maintain the sparkle of your favourite pieces.
What is Oxidation?
Oxidation is a chemical reaction that occurs when a metal is exposed to oxygen in the air. As the metal reacts with the oxygen, it forms a thin layer of oxide on the surface, which can change the appearance of the metal.
In the case of jewellery, the most common metals used are gold, silver, and copper. Each of these metals has a unique way of reacting to oxygen, which can result in different types of oxidation.
Silver Oxidation
Silver is a popular choice for jewellery because of its beautiful, lustrous appearance. However, silver is also highly reactive to oxygen, which can cause it to tarnish over time. The tarnish is a result of the silver reacting with sulfur compounds in the air, forming a thin layer of silver sulfide on the surface.
Gold Oxidation
Gold, on the other hand, is much less reactive to oxygen, which is why it's often considered a more durable option for jewellery. However, gold can still experience a form of oxidation called discoloration, where the metal takes on a yellowish or brownish hue.
Copper Oxidation
Copper is another metal commonly used in jewellery, and it's known for its reddish-brown colour. When copper is exposed to oxygen, it can develop a greenish-blue patina, which is a type of oxidation. This patina is often considered a desirable feature in certain types of jewellery, such as antique or vintage pieces.
Preventing Oxidation
While oxidation is a natural process that can't be completely avoided, there are some steps you can take to help slow it down and keep your jewellery looking its best:
- Store your jewellery properly: Keep your pieces in a cool, dry place, away from direct sunlight and moisture.
- Clean your jewellery regularly: Use a soft cloth or a mild jewellery cleaner to gently remove any dirt or debris that could accelerate the oxidation process.
- Avoid exposure to harsh chemicals: Chemicals like chlorine, bleach, and even certain household cleaners can react with the metal in your jewellery and cause it to tarnish.
By understanding the science behind oxidation and taking good care of your jewellery, you can help ensure that your favourite pieces continue to sparkle and shine for years to come.
