925 Sterling Silver Explained: Why We Choose Solid Silver Over Plated Alternatives
From Nickel Silver to Solid Silver: A Honest Conversation About Durability and Legacy
The Question We Get Most Often
"Why does your silver version cost significantly more?" The answer lies in what "925" actually means.
What Is 925 Sterling Silver?
Sterling silver is not a marketing term — it's a metallurgical standard dating back to 7th century England. The "925" hallmark certifies 92.5% pure silver content, with the remaining 7.5% typically copper for structural integrity.
Every IGNIS ARGENTUM piece carries the 925 stamp — a certification of authenticity, not just a marketing symbol.
Sterling Silver vs. Nickel Silver: A Critical Distinction
Nickel Silver contains no silver at all. It's a copper-nickel-zinc alloy that happens to look silvery. We offer it as an accessible option, but we're transparent: it's base metal, not precious metal.
After three years of daily use: sterling silver (left) develops warm patina, while nickel silver (right) shows industrial wear patterns.
Why This Matters for Daily Carry
Your key case lives in your pocket. It experiences temperature changes, humidity, friction, and the occasional drop. Sterling silver develops a patina — a soft, warm sheen that tells the story of years. Nickel Silver merely wears down.
The Patina Question
Yes, sterling silver tarnishes. This is not a defect — it's chemistry. Silver reacts with sulfur compounds in the air, forming silver sulfide. A quick polish restores brilliance. Or let it develop character. Both are valid.
Patina progression: new (top), 6 months (middle), 2 years (bottom). Each stage has its own beauty.
