Does Sterling Silver Tarnish?
Yes, sterling silver does tarnish over time. Sterling silver is made up of 92.5% pure silver, with the remaining 7.5% consisting of other metals (usually copper) to make it more durable. This combination gives sterling silver it's strength but also makes it prone to tarnishing - a chemical reaction that occurs when silver reacts with sulfur compounds in the air.
The good news is that tarnishing isn't permanent! With a little care, your jewellery can look as good as new. Factors like humidity, pollution, and everyday use (think sweat, perfumes, and beauty products) can speed up the tarnishing process, so knowing how to care for your silver is the key to maintaining its beautiful shine.
What Causes Tarnishing?
Tarnish occurs when sterling silver reacts with certain environmental and chemical factors. Here are the main culprits:
- Humidity and Pollution: High humidity and exposure to polluted air can cause silver to tarnish faster, especially if you live in a coastal or urban area.
- Beauty Products and Chemicals: Perfumes, lotions, and even hairsprays contain chemicals that can accelerate tarnish. Chlorine in pools is especially harsh on silver.
- Skin Oils and Sweat: Natural oils and sweat from your skin also contribute to tarnishing, particularly if your jewellery is worn daily.
Understanding these factors can help you take steps to minimise tarnishing and keep your silver looking bright.
