When you shop for handmade jewellery you’ll often see two materials mentioned: 925 sterling silver and stainless steel. Both are excellent, but they suit different needs. Here’s a clear comparison to help you choose.
What is 925 sterling silver?
“925” means the metal is 92.5% pure silver, mixed with a small amount of copper for strength. It is a precious metal with a warm, luminous shine that stainless steel cannot quite replicate. It is the traditional choice for fine, heirloom-quality pieces — and it is what we use for the heart of the Castello signature line.
- Look: soft, bright, precious glow.
- Value: a genuine precious metal.
- Care: can tarnish slowly over time, but polishes back to full shine easily (more below).
- Skin: hypoallergenic for most people.
What is stainless steel?
Stainless steel is a highly durable alloy prized for being tough and low-maintenance. It resists tarnishing and scratches, and stands up well to water and daily wear.
- Look: cooler, modern sheen.
- Durability: extremely hard-wearing.
- Care: virtually maintenance-free.
- Skin: hypoallergenic and very sweat-resistant.
Which should you choose?
Choose 925 sterling silver if you want a precious, timeless piece with a warm shine — ideal for gifts and everyday elegance. Choose stainless steel if you want something rugged and low-maintenance for sport, water or heavy daily wear.
Caring for sterling silver
Keep it dry, avoid perfume, lotions and chlorine, remove it before swimming or showering, and store pieces separately. A gentle wipe with a soft cloth keeps it bright — and any natural stones stay beautiful with the same care.
