Sterling Silver Is 92.5 Percent Silver, and the Other 7.5 Is the Point

Author : hitzcart mujtaba | Published On : 22 Oct 2026

Sterling silver is an alloy of 92.5 percent silver and 7.5 percent other metal, usually copper. The 925 stamp on a piece records that ratio. Pure silver is too soft to hold a clasp or a setting in daily wear, so the added metal is what makes silver jewellery wearable rather than what makes it cheaper.

That ratio also explains how sterling ages. The copper content is what reacts with sulphur in air and on skin to produce tarnish, and it is why sterling darkens while pure silver barely does.

What a charm range actually consists of

The figures below come from a catalogue audit of 123 live listings from one charm-jewellery brand, discontinued stock excluded, captured in August.

Type	Live listings
Charm	54
Ring	30
Bracelet	23
Necklace	12
Safety chain	1

82 of the 123 listings reference silver and 37 reference cubic zirconia stones.

Charms outnumber bracelets by more than two to one, which is the whole business model visible in a table. A bracelet is bought once and charms are added over years, so a range built around that system needs far more charms than bracelets to work.

How the charm system actually holds together

Threaded bracelets carry a short screw thread at each end, and charms with matching internal threads lock onto it rather than sliding freely. Clips sit at intervals to divide the bracelet into sections, which stops charms bunching together and spreads the weight.

Safety chains attach across the clasp so that if the clasp opens, the bracelet stays on the wrist. On a bracelet carrying a dozen charms, that matters more than it sounds.

Spacers keep charms from rubbing directly against each other, which reduces wear on plated and enamelled pieces in particular.

Weight is the limit nobody mentions. A bracelet carrying a dozen or more charms pulls on the clasp and the thread with every movement, and the clasp is the part that eventually wears. Spreading charms evenly between clips and keeping the heaviest pieces near the centre slows that wear considerably.

The charm and bracelet range sits in the Pandora collection.

Caring for sterling without damaging it

Wear it. Friction against skin and clothing keeps the surface clean, so a bracelet worn daily tarnishes more slowly than one left in a drawer.

Store it sealed. An airtight bag or a box with an anti-tarnish strip slows the sulphur reaction considerably.

Take it off for chlorine and sulphur-rich water. Pools and some spa water accelerate tarnish sharply.

Polish with a proper silver cloth rather than paste. Paste is abrasive and removes metal along with the tarnish, and it can strip the oxidised detail some charms are designed to carry.

Cubic zirconia stones need separate care. They are hard enough to resist scratching, but the settings that hold them are silver and can loosen with knocks.

Check the prongs every few months on any stone-set piece worn daily. A prong that has lifted slightly is easy for a jeweller to close and impossible to fix once the stone has gone. Rings take the most impact of any jewellery type, which is why stone loss is far more common on rings than on charms or pendants.

Sterling against the alternatives

Steel jewellery does not tarnish at all and survives water, which is its main advantage. It is also harder, cooler on the skin and holds no metal value.

Gold-plated pieces look warmer but wear through to the base metal over time, and how they age depends entirely on what sits underneath.

Sterling sits between the two: warmer than steel, more durable than thin plating, and it needs a few minutes with a cloth now and then.

Steel alternatives sit in the Morellato steel jewellery range.

Gold-tone pieces run through the La Petite Story collection.

Who this suits

If you want jewellery that builds over years and carries meaning in the pieces chosen, the charm system works exactly as designed. If you want something you never have to clean, steel is the more practical material and costs less.

Frequently asked questions

What does 925 mean on silver jewellery?

It means the piece is sterling silver, an alloy of 92.5 percent silver and 7.5 percent other metal, usually copper. Pure silver is too soft for daily wear, so the added metal is what makes sterling strong enough to hold clasps and settings.

Why does sterling silver tarnish?

Because the copper in the alloy reacts with sulphur compounds in air and on skin, forming a dark surface layer. Daily wear slows it, since friction keeps the surface clean, while pieces stored in open air tarnish faster than those kept sealed.

How does a charm bracelet system work?

Threaded bracelets carry screw threads at each end, and charms with matching internal threads lock onto them. Clips divide the bracelet into sections to stop charms bunching, and a safety chain across the clasp keeps the bracelet on if the clasp opens.

Why are there more charms than bracelets in a range?

Because the bracelet is bought once and charms are added over years, often as gifts marking particular occasions. In one audit of 123 listings, charms outnumbered bracelets 54 to 23, which reflects how the system is actually bought and worn rather than how it is first purchased.

How should I clean sterling silver?

Use a dedicated silver polishing cloth rather than paste, which is abrasive and removes metal along with tarnish. Store pieces in a sealed bag when not worn, and remove them before swimming in chlorinated water, which accelerates tarnishing. How a piece ages depends far more on wear and storage than on the brand.

Is sterling silver better than stainless steel?

Neither is better outright. Sterling looks warmer and holds metal value but needs occasional polishing. Stainless steel never tarnishes and survives water, but feels cooler, harder, and holds no material value. The choice depends on how much maintenance you want.
