If you have ever shopped for silver jewellery, you have almost certainly come across standard sterling silver. It is the industry standard — the default alloy used by most jewellers worldwide for centuries. But Argentium silver is increasingly being chosen by jewellers and buyers who want more from their silver. Here is a clear comparison of the two.
Composition
Standard Sterling silver is 92.5% pure silver and 7.5% copper. That ratio has remained largely unchanged since the 12th century.
Argentium silver is available in two grades — 935 and 960 — meaning it contains between 93.5% and 96% pure silver. The remaining percentage includes both copper and germanium, with germanium being the key difference.
Tarnish Resistance
This is the most significant practical difference between the two metals. Standard Sterling silver tarnishes because the copper it contains reacts with sulphur and oxygen in the atmosphere. The tarnishing process is accelerated by humidity, perfume, sweat, and everyday wear.
Argentium silver is significantly more resistant to tarnish. The germanium in the alloy forms a stable oxide layer on the surface that acts as a barrier, dramatically slowing the tarnishing process. Most Argentium silver owners find they need to clean their jewellery far less frequently than with sterling.
Skin Sensitivity
Standard Sterling silver can cause reactions in people with copper or nickel sensitivity — a common issue since many sterling alloys also contain trace amounts of nickel.
Argentium silver contains no nickel and lower copper levels, making it a naturally hypoallergenic choice. It is widely recommended by jewellers for customers with sensitive skin or metal allergies.
Hardness and Durability
Interestingly, Argentium silver can be made harder than Standard sterling silver through a process called precipitation hardening. This makes it more resistant to scratching and denting — a practical advantage for rings and bracelets that take daily wear.
Sustainability
Argentium silver is produced using recycled silver, making it a more environmentally responsible choice than conventionally mined sterling silver. For buyers who care about the origin and impact of their purchases, this is an increasingly important consideration.
Price
Argentium silver typically costs slightly more than standard sterling silver due to its higher silver content and the inclusion of germanium. However for most finished jewellery pieces the price difference is modest — and given the reduced need for cleaning, replating, or replacement, many buyers consider it better long-term value.
Which Should You Choose?
If you want jewellery you can wear daily, that will stay brighter for longer, is kind to sensitive skin, and is made with responsible materials — Argentium silver is the better choice. Standard Sterling silver remains a fine metal with a long history, but for modern everyday wear, Argentium represents a meaningful step forward.
