At Smith Jewels, we pride ourselves on offering the finest 925 sterling silver jewellery. However, one common concern many silver jewellery owners face is the phenomenon of their pieces turning black. This blog will delve into the reasons behind this discolouration, how to clean and prevent it, and reassure you about the authenticity of your silver jewellery.
The Science Behind Silver Tarnishing
Silver tarnishing occurs due to a chemical reaction between silver and sulfur-containing substances in the air. This process, called oxidation, results in the formation of silver sulfide, which appears as a black coating on the surface of the jewellery. Here’s a simple breakdown:
- Exposure to Sulfur: Sulfur compounds are present in the air, particularly in polluted environments. When silver comes into contact with these compounds, it reacts to form silver sulfide.
- Moisture and Humidity: High humidity levels and exposure to moisture can accelerate the tarnishing process.
- Personal Care Products: Perfumes, lotions, and other personal care products containing sulfur can also cause silver to tarnish more quickly.
Is Tarnished Silver Fake?
Absolutely not! Tarnishing is a natural process that happens to all real silver over time. In fact, it is a sign that your jewelry is made of genuine silver. Fake silver, often made of metals like nickel or coated in a silver-coloured finish, does not tarnish in the same way.
How to Clean Tarnished Silver?
If your silver jewellery has turned black, don’t worry. Cleaning it at home is easy with the following method:
DIY Cleaning Method
1. Materials Needed: Aluminum foil, baking soda, hot water, and a bowl.
2. Steps:
- Line the bowl with aluminum foil.
- Add hot water and a tablespoon of baking soda.
- Place your silver jewellery in the bowl, ensuring it touches the aluminum foil. The tarnish will start to transfer from the silver to the foil due to a chemical reaction.
- Let it sit for a few minutes, then remove and rinse with clean water.
- Dry with a soft cloth.
For heavily tarnished pieces or for professional results, you can always bring your jewellery to a professional cleaner.
Preventing Silver from Turning Black
To keep your 925 silver jewellery looking its best, follow these preventive tips:
1. Store Properly: Keep your silver in airtight containers or jewellery boxes lined with anti-tarnish cloth.
2. Avoid Exposure: Remove your jewellery before swimming, showering, or applying personal care products.
3. Regular Cleaning: Clean your silver regularly with a soft polishing cloth to remove oils and dirt that can cause tarnish.
4. Use Anti-Tarnish Strips: Place anti-tarnish strips in your jewellery box to absorb sulfur compounds.
Why Silver Turns Green or Red
- Green: Silver can turn green when it reacts with acids in sweat or certain chemicals, especially if it contains copper (as sterling silver does). This reaction forms copper carbonate, which is green.
- Red: A reddish hue can appear if silver reacts with certain chemicals or extreme environments, but this is less common and usually indicates a specific type of chemical exposure.
