There is a question we rarely ask ourselves in the moment we fall in love with a piece: what is it truly made of?
This is not a technical detail. It is the difference between a piece of jewellery that stays with you for years — and one that leaves marks on your skin.
Not Everything That Gleams Is Silver
The market is full of pieces that look like silver. That have the right shine, the right weight, the right appearance. But beneath the plating, many conceal alloys containing nickel — one of the leading causes of contact allergies: itching, redness, dermatitis. Present in countless low-cost pieces, nickel is the ingredient no one mentions.
At CINCO, every piece is hypoallergenic and nickel-free. This is not a selling point. It is a conviction.
The Composition That Makes All the Difference
925 silver — also known as sterling silver — is not pure silver. And that is precisely what makes it superior.
It is composed of 92.5% pure silver and 7.5% carefully selected alloys: copper, zinc, tin and silicon. Each element serves a purpose:
- Copper — provides strength and structure to the alloy, with a minimal allergy index
- Zinc and tin — refine the finish and enhance resistance to oxidation
- Silicon — stabilises the alloy, ensuring greater durability and safety
The result is a piece of jewellery that does not merely shine — it endures the rhythm of your life.
Why This Knowledge Matters
When you choose a piece of jewellery, you are choosing something that will be in contact with your skin every single day. On your wrist as you work. Around your neck when you embrace someone. On your fingers as you move through the world.
Understanding the composition is not being technical. It is being conscious. It is caring for your body with the same intention with which you care for your style. Learn how to care for your jewellery to keep it looking its best for years to come.
At CINCO, every piece is designed and handmade in Portugal, certified by the INCM, and crafted to last — not merely to impress at first glance.
The Choice That Remains
A 925 silver piece is not an impulse purchase. It is an investment in something that ages with you, that accumulates meaning, that can be passed down through generations.
Because, in the end, what distinguishes a truly fine piece of jewellery is not only what you see. It is what lies within.
