Why does 925 silver tarnish?
925 silver, also known as sterling silver, is composed of 92.5% pure silver and the remaining 7.5% of other metals, usually copper. This alloy gives the jewelry strength but exposes the silver to oxidation: upon contact with air, humidity, and certain chemicals, the surface can darken over time. This is a natural process, not a defect.
How to clean 925 silver jewelry
Routine cleaning is simple and can be done at home:
- Soft cloth: use a microfiber cloth or a dedicated silver polishing cloth to gently polish the surface after each use.
- Warm water and neutral soap: immerse the jewelry for a few minutes, rub with a soft cloth, and dry thoroughly.
- Baking soda: for more stubborn tarnishing, create a paste with baking soda and water, apply with a soft cloth, and rinse well.
Avoid hard toothbrushes, abrasive products, and ultrasonic cleaners for jewelry with stones or enamel.
How to store silver jewelry
Proper storage is essential to slow down oxidation:
- Store each piece of jewelry separately in anti-tarnish bags or in an airtight box.
- Avoid humid environments like the bathroom — prefer a dry drawer or a dedicated case.
- Place a sachet of silica gel in the box to absorb moisture.
What to absolutely avoid
Certain behaviors accelerate the deterioration of 925 silver jewelry:
- Contact with perfumes, creams, hairspray, and detergents.
- Wearing jewelry in the pool or at the beach (chlorine and salt are enemies of silver).
- Leaving jewelry exposed to direct sunlight for long periods.
When to consult a professional
If the jewelry shows deep tarnish, obvious scratches, or loose stones, it is advisable to consult a jeweler. Professional cleaning and possible rhodium plating can restore the jewelry to its original brilliance.
