What is argentium Silver?

About Argentium Silver

A New Kind of Silver
In 1991, after ten years of research, silversmith Peter Johns created Argentium Silver. He wanted to solve a problem called firestain — the dark marks that appear on regular silver when it’s heated. His discovery changed how fine silver jewellery is made.

The Problem of Firestain
Firestain happens when heat reacts with copper inside sterling silver. Because jewellers need heat to shape and solder metal, the issue was impossible to avoid — until Johns added a small amount of germanium to silver. That tiny change stopped firestain completely. The germanium forms a clear, protective layer when heated, keeping the surface bright and clean.

Stronger and Safer
Argentium Silver is also nickel-free, so it’s gentle on sensitive skin. It’s harder and more scratch-resistant than traditional sterling, which means it stays bright longer and needs less polishing. It’s the perfect silver for everyday wear or travel.

Clean Bonds and Bright Finish
Argentium can be joined to itself or even to gold without heavy soldering, so the joins stay strong and seamless. It’s also naturally whiter and brighter than standard sterling, giving it a lasting, luminous shine.

Why We Use It
Every piece of A & R Jewellery is made from Argentium Silver — even the earwires and jump rings. We choose it because it resists tarnish, feels comfortable on the skin, and keeps its brilliance for years. Each piece reflects the care and precision that go into every design.
