If you've ever looked for silver jewellery online, you've surely seen these names: 925 silver, sterling silver and Italian silver. And you may have wondered whether they are different materials or whether one is better than another. The answer is simple: they are exactly the same. We explain why, with examples of pieces from our shop.
What is 925 silver?
The number 925 shows the purity of the metal in thousandths. A piece of 925 silver contains 925 parts silver out of 1,000, that is, 92.5% silver. The remaining 7.5% is an alloy of other metals, usually copper.
It is the most widely used standard in jewellery in Spain and in most of the world. When a piece is stamped with the number 925, usually inside the ring, on the clasp or on the bail, it shows it has this standard.
Why isn't 100% pure silver used?
Pure silver, also called fine silver or 999 silver, is 99.9% silver. The problem is that it is too soft for jewellery: it scratches easily and bends with knocks.
Mixing it with a small amount of copper produces a much stronger alloy that keeps the colour of silver and stands up to everyday wear. That is 925 silver.
And sterling silver?
Sterling silver is the same as 925 silver. The name has been used in England since the Middle Ages for silver of this purity. Today sterling silver and 925 silver are synonyms.
And "plata de ley"?
Plata de ley is the name used in Spain for this same standard: silver with at least 925 thousandths of silver.
So: plata de ley = 925 silver = sterling silver. Three names, one material.
So what is Italian silver?
The term Italian silver is not an official name and does not appear in any regulation. It is a popular name that began to be used for silver jewellery made in Italy, known for its craftsmanship, and that many people now use to refer to good-quality 925 silver, wherever it was made.
How do I know if a piece is genuine 925 silver?
Look for the number 925 stamped on the piece. In Spain silver jewellery carries this hallmark, although very small pieces may not because of their size. If in doubt, a jeweller can check it.
Be wary of jewellery advertised as "silver" or "solid silver" at very low prices. Often it is steel, silver plating or costume jewellery: a thin layer that wears away and reveals another metal underneath.
Does silver tarnish?
Yes, over time sterling silver darkens through contact with air, sweat, perfumes or creams. It's normal and doesn't mean it isn't silver. To slow it down, store it in a closed pouch and take it off to shower or go swimming.
To restore its shine, all you need is a specific silver cleaning product, like the one we sell in our shop.
Does silver cause allergies?
Sterling silver contains 7.5% other metals, usually copper. Most people wear it without any problem, but if you have a known allergy to a metal, ask us before buying and we'll tell you which pieces suit you.
