Argentium silver is a modern silver alloy that contains a higher percentage of pure silver than traditional sterling silver, combined with germanium — a rare metalloid that gives it exceptional properties not found in any other silver alloy on the market today.
The Science Behind Argentium Silver
Standard sterling silver is made of 92.5% pure silver and 7.5% copper. That copper content, while necessary for durability, is also the primary reason sterling silver tarnishes. When copper reacts with oxygen and sulphur in the air, it forms a dark layer on the surface — the familiar blackening most silver owners know well.
Argentium silver replaces a portion of that copper with germanium. The result is an alloy that is more resistant to tarnish, naturally antibacterial, and kinder to sensitive skin — all without sacrificing the beauty or durability that makes silver such a popular choice for fine jewellery.
What Makes Argentium Silver Different
There are two grades of Argentium silver currently available — 935 and 960 — both of which contain more pure silver than sterling's 92.5% standard. The higher the silver content, the brighter and more lustrous the metal.
The germanium content does several important things. It creates a protective oxide layer on the surface of the metal that resists tarnish far more effectively than copper-based alloys. It also gives Argentium its natural antibacterial qualities, making it an excellent choice for earrings, rings, and bracelets worn directly against the skin every day.
Is Argentium Silver Real Silver?
Yes. Argentium silver is fully hallmarkable and recognised by the British Hallmarking Council. It is certified, regulated, and held to the same standards as any other precious metal sold in the UK. It is not a plated metal — it is solid silver throughout.
Who Is Argentium Silver For?
Argentium silver is ideal for anyone who loves the look of silver jewellery but has experienced tarnishing, skin reactions, or the frustration of constant polishing. It is particularly well suited to people with sensitive skin or nickel allergies, those who want jewellery they can wear every day without special care, and anyone looking for a more sustainable and responsible choice — Argentium is produced using recycled silver.
