Jewellery is designed to be worn, lived in, and loved—but like all beautiful things, it responds to its environment. Over time, some metals naturally change, developing a patina or tarnish that reflects wear and exposure. Understanding why jewellery tarnishes—and how to care for it—helps preserve both its beauty and longevity.
What Is Tarnish?
Tarnish is a surface reaction that occurs when certain metals interact with elements in the air or on the skin. It often appears as a dulling, darkening, or discolouration on the surface of jewellery. Tarnish does not mean your jewellery is poor quality—it is simply a natural process, especially in precious metals.
Which Metals Tarnish—and Why
Different metals react differently over time:
Sterling Silver
Sterling silver contains a small amount of copper for strength. When exposed to air, moisture, or sulphur compounds, it can darken. This is one of the most common and easily reversible forms of tarnish.
Gold & Gold-Plated Jewellery
Solid gold does not tarnish, but lower-karat gold alloys may dull slightly over time due to mixed metals. Gold-plated jewellery can show wear as the outer layer thins with friction and exposure.
Rose Gold
Rose gold contains copper, which can react with moisture and skin oils. This may create a subtle patina over time, often experienced as warmth deepening rather than dullness.
Brushed or Matte Finishes
Textured finishes can make tarnish more noticeable simply because of their surface area, though they often age beautifully with gentle wear.
Everyday Causes of Tarnishing
Jewellery is exposed to more than we realise. Common contributors include:
- Humidity and moisture
- Perfume, skincare, and cosmetics
- Sweat and natural skin oils
- Cleaning products and chemicals
- Air pollution and salt (especially coastal environments)
Even how jewellery is stored plays a role.
How to Prevent Jewellery Tarnish
While tarnish can’t always be avoided, it can be significantly slowed with thoughtful care.
Store Jewellery Properly
Keep pieces in a dry, airtight environment when not in use. Soft pouches, lined jewellery boxes, or sealed bags help limit air exposure.
Put Jewellery on Last
Apply skincare, perfume, and makeup before wearing jewellery. This simple habit reduces direct contact with chemicals that accelerate tarnishing.
Remove Before Water Exposure
Take jewellery off before showering, swimming, or exercising. Water, chlorine, and salt can all affect metal surfaces.
Clean Gently and Regularly
A soft polishing cloth used occasionally helps remove surface build-up before it becomes noticeable. Avoid harsh cleaners or abrasive materials.
Wear It Often
Surprisingly, regular wear—especially of silver—can help prevent tarnish by limiting prolonged exposure to air.
Embracing Natural Patina
Not all change is something to correct. Many jewellery lovers appreciate the way metals soften and deepen over time. A gentle patina can add character, depth, and individuality—making a piece uniquely yours.
At Alexandra, our jewellery is designed to age gracefully, evolving alongside the person who wears it. With simple care and intention, each piece can be worn and loved for years to come.
