Sterling silver is one of the most widely used metals in quality jewellery. Its clean, cool-toned shine pairs well with natural stones, it is durable enough for everyday wear, and it is available at a wide range of price points. This guide covers what sterling silver is, why it is used in crystal jewellery, and how to keep it in good condition.
What is sterling silver?
Sterling silver is an alloy composed of 92.5% pure silver and 7.5% other metals, usually copper. Pure silver (99.9%) is too soft to hold its shape well in jewellery, so copper is added to improve durability while retaining the characteristic silver appearance. Sterling silver pieces carry a 925 hallmark to indicate this composition.
How to identify sterling silver
In the UK, hallmarked silver jewellery carries a 925 stamp or the lion passant mark applied by an Assay Office. When buying silver jewellery, look for a visible hallmark on the clasp, inside the band, or on the back of a pendant. Pieces described only as "silver-coloured" or "silver-tone" without a hallmark are likely silver-plated or made from a base metal alloy rather than sterling silver.
Sterling silver vs silver-plated jewellery
Silver-plated jewellery has a thin layer of silver over a base metal, often brass or copper. That plating wears through over time, exposing the metal beneath. Sterling silver is solid throughout, making it more durable and longer-lasting for regular wear. Browse our crystal jewellery collection, which includes pieces made with sterling silver settings.
Why is sterling silver used in crystal jewellery?
Silver's neutral, cool tone complements the natural colours of most crystals without competing with the stone itself. It also allows for detailed settings that hold stones securely. Compared to gold, silver is more accessible in price, making it the standard choice for handmade crystal jewellery across a wide range of styles.
Common settings in crystal jewellery
- Bezel setting: a collar of silver wraps around the edge of the stone, holding it flat against the piece. Secure and clean-lined.
- Wire wrapping: fine silver wire is coiled around the stone. Used for pendants and rings with irregular-shaped stones.
- Prong setting: small silver prongs grip the stone from above, allowing maximum visibility of the stone's surface and colour.
- Channel setting: stones sit in a channel cut into the silver band, common in tennis bracelets with a continuous line of stones.

Silver bracelets Crystal necklacesA brief history of silver in jewellery
Silver has been used in jewellery and decorative objects for thousands of years. In ancient civilisations including Egypt, Greece and Rome, silver appeared in amulets, rings and ceremonial objects. Across many cultures, silver was associated with the moon, used in coinage and traded as a store of value. In the UK, the hallmarking system for silver has been in operation since the 14th century, making it one of the oldest consumer protection measures still running today.
How to care for sterling silver jewellery
Why silver tarnishes
Sterling silver tarnishes when exposed to sulphur compounds in the air. These react with the silver to form silver sulphide, the dark layer visible on tarnished pieces. This is a natural and reversible chemical process, not damage to the metal. Moisture, perfumes, lotions and certain foods can accelerate tarnishing.
How to clean silver jewellery at home
For light tarnish, a soft silver polishing cloth is the simplest and safest method. Rub gently in one direction rather than in circular motions. For more significant tarnish, a small amount of mild washing-up liquid in warm water, applied with a soft cloth and rinsed thoroughly, works on most sterling silver pieces. Dry immediately and completely after washing. Avoid abrasive cloths or pastes, which can scratch the surface.
Caring for silver jewellery with crystal settings
When cleaning silver pieces with crystal or gemstone settings, check first whether the stone is water-safe. Selenite, Malachite, Pyrite and some other minerals should not get wet. For these pieces, use only dry polishing cloths on the silver parts. For water-safe stones (quartz varieties, agate, onyx), a damp cloth is fine for the whole piece. Full care guidance is in our article: How to Clean Crystal Jewellery Safely.
Storing silver jewellery
Store sterling silver in a dry, sealed pouch or box. Anti-tarnish pouches or strips slow the tarnishing process significantly. Keep pieces away from humidity, direct sunlight and other metals that may cause scratching. Store individual pieces separately where possible.
Daily wear tips
Remove silver jewellery before swimming (chlorine and salt water accelerate tarnishing), showering, washing up, applying skincare or perfume, and before heavy exercise. Put jewellery on last when getting ready, after applying lotions and sprays.
Rhodium-plated silver: what to know
Some sterling silver jewellery is plated with a thin layer of rhodium, a platinum-group metal, which gives a brighter, more reflective finish and significantly reduces tarnishing. Rhodium-plated silver requires the same basic care as unplated silver but should not be polished aggressively as the plating can wear through over time. Replating requires a professional jeweller.
Frequently asked questions
What does 925 mean on silver jewellery?
925 is the hallmark for sterling silver, indicating that the piece contains 92.5% pure silver. It is the standard for quality silver jewellery in the UK and internationally. Look for this stamp on the clasp, inside a ring band, or on the back of a pendant.
Does sterling silver turn skin green?
Pure sterling silver does not normally turn skin green. Discolouration is more commonly associated with copper-heavy alloys or low-quality plated pieces where the base metal is exposed. If you experience discolouration from a 925 sterling silver piece, it may indicate a reaction to the copper content (7.5%), which is uncommon but possible in people with very sensitive skin.
How do I remove heavy tarnish from silver?
For heavily tarnished pieces without delicate stones or plating, a bicarbonate of soda paste mixed with a small amount of water, applied with a soft cloth and rinsed thoroughly, can remove significant tarnish. Commercial silver dip solutions work quickly but can be too aggressive for delicate settings or plated pieces. When in doubt, use a polishing cloth or take heavily tarnished pieces to a jeweller.
Is sterling silver hypoallergenic?
Sterling silver is well-tolerated by most people, but it is not fully hypoallergenic because of its copper content. People with confirmed copper allergies may react to sterling silver. If you have a known metal allergy, check the full metal composition before buying, or opt for fine silver (999) or platinum settings where available.
How can I tell if silver jewellery is good quality?
Look for a 925 hallmark, secure settings with no visible gaps, smooth edges and a consistent finish. In the UK, hallmarked silver has been independently tested by an Assay Office, which provides a guarantee of metal content. Buy from sellers who clearly describe their materials and provide a returns policy.
