Sterling silver combines enduring strength with a bright, refined finish. It is however prone to tarnishing when exposed to certain chemicals, moisture or environmental factors. In this article, we will explain why silver discolours, how quickly it can occur, and practical steps to maintain your pieces’ original lustre. At Cleopatra’s Bling we personally love the old-world patina that a little oxidation gives a piece, enhancing its texture and lending it an authentic historical feel.
Tarnish develops when silver reacts with sulphur compounds in the air or in everyday products such as lotions, perfumes or certain storage materials. The outcome is a thin layer of silver sulphide that masks the metal’s natural shine. Humidity accelerates this reaction because moisture makes oxidation happen more rapidly. Depending on your environment and care routine, you might notice slight discolouration within hours, or enjoy years of shine before any change.
Indeed, these simple approaches significantly reduce oxidation:
Sterling silver consists of 92.5% pure silver alloyed with 7.5% copper (sometimes other metals) to improve strength. This balance delivers a resilient metal that retains a bright finish suitable for everyday jewellery.
The “925” hallmark signifies this precise ratio. At Cleopatra’s Bling, each piece, such as our Handmade Snake Chain, Sterling Silver, bears that mark along with our “CB” stamp, confirming both purity and provenance.
Nearly pure silver (above 99%) is too soft for functional jewellery. Some mass-market items use plating or coatings to resist tarnish, but these layers can wear away. Properly cared-for sterling silver remains the most reliable choice for enduring quality.
Tarnish appears when silver comes into contact with small amounts of sulphur—whether from the air, your favourite lotion or certain household products—creating a thin layer of silver sulphide on the surface. You may first notice a faint yellow or brown shade that gradually deepens into grey or black. The good news is that this change only affects the exterior and can be reversed with a gentle clean.
In humid or polluted environments, you might spot early tarnish within a couple of days.
Stored in a cool, dry place, your silver can stay bright for weeks or months before showing signs of discolouration.
As the silver sulphide layer becomes thicker, it absorbs light rather than reflecting it. A simple polish removes that layer, revealing the original shine beneath.
Preventing tarnish is more straightforward than removing it later. These strategies help keep your silver’s original brilliance.
Even with prevention, deep cleaning may occasionally be required.
For intricate or heavily tarnished pieces, trust a reputable jeweller’s ultrasonic or steam-cleaning services.
Tarnish is a natural part of silver’s life cycle, but it doesn’t have to be permanent. By understanding how and why silver tarnishes, and applying straightforward care routines from Cleopatra’s Bling, you’ll keep your pieces radiant through every season.

Does sterling silver tarnish?
Yes. Sterling silver naturally tarnishes over time when it reacts with sulphur compounds in the air or in everyday products such as lotions, perfumes, and certain storage materials. This creates a thin layer of silver sulphide that dulls the surface.
How quickly can sterling silver tarnish?
It depends on your environment. In humid or coastal areas, fine pieces may begin to dull within 24–48 hours. In average indoor conditions, tarnish may take weeks or months, while properly stored silver can stay bright for years.
Why does sterling silver turn dark or black?
As silver reacts with sulphur, the silver sulphide layer thickens. The thicker it becomes, the more light it absorbs instead of reflecting, which is why the surface can shift from faint yellow-brown tones to darker greys and black.
What is sterling silver made of?
Sterling silver is made from 92.5% pure silver mixed with 7.5% copper (and sometimes other metals). This alloy strengthens the silver so it is suitable for everyday jewellery while still maintaining its bright finish.
How can I tell if my jewellery is genuine sterling silver?
Look for a “925” hallmark, which confirms the 92.5% silver content. Cleopatra’s Bling sterling silver pieces are also stamped with “CB”. Genuine sterling silver is typically non-magnetic and develops a subtle patina over time.
What causes sterling silver to tarnish faster?
Humidity is one of the biggest factors, as moisture speeds up oxidation. Tarnish is also accelerated by exposure to perfume, hairspray, lotions, salt water, chlorinated water, and even individual skin chemistry, as everyone’s natural oils and pH levels differ.
How do I prevent sterling silver from tarnishing?
To reduce tarnish, store your jewellery in airtight containers or resealable pouches, ideally with silica gel or chalk to absorb moisture. Put silver on after skincare and fragrance, and wear it regularly, as natural skin oils can help protect the surface.
What is the best way to clean tarnished sterling silver at home?
A trusted method is the foil-and-bicarbonate soak: line a dish with foil, add warm water and a tablespoon of bicarbonate of soda, soak briefly, then rinse and dry thoroughly. For everyday care, a soft polishing cloth or mild soapy water also works well.
