How to Care for Your Jewellery, Understand Your Metals, and Build a Lifelong Relationship with What You Wear

Fine jewellery isn’t meant to live in boxes, it’s meant to live with you. Every piece you own carries both memory and material: stories of gold, gemstone, and the life you’ve shared.

This guide is here to help you understand those materials, care for them, and keep their light lasting.

What Is the Difference Between 9ct and 18ct Gold?

Both are solid gold, the distinction lies in purity and tone.

• 9ct gold contains 37.5% pure gold, balanced with alloys like silver or copper for strength. Its colour is slightly paler, warm and practical for everyday wear.

• 18ct gold is 75% pure gold, richer in hue and softer to the touch. It carries a deeper lustre and resists tarnish beautifully.

We use both across the Icons Collection, 18ct for depth and luxury, 9ct for those who prefer understated resilience.
Whichever you choose, both are built to last a lifetime when cared for with intention.

Can You Wear Gold Every Day?

Yes. Gold is naturally resistant to rust and tarnish, which is why it’s been treasured for millennia. Daily wear develops a soft patina, a subtle polish from your own movements, giving each ring its quiet individuality.

To keep its brilliance, avoid chlorine, harsh cleaning products, and long soaks in water.
Remove your jewellery before swimming or cleaning, then simply wipe it with a soft cloth before bed.

How Should You Clean Gold Jewellery at Home?

The simplest care routine is often the best:

1. Fill a bowl with warm water and a drop of mild soap.

2. Let your jewellery soak for a few minutes.

3. Gently brush crevices with a soft toothbrush.

4. Rinse thoroughly and pat dry with a lint-free cloth.

Never use bleach or strong detergents — they can weaken gold alloys.

For gemstone pieces (especially opal, emerald, and aquamarine), avoid ultrasonic or steam cleaners. Instead, use a gentle wipe and mindfulness — a daily ritual that honours both material and meaning.

Why Does Gold Change Colour Over Time?

All precious metals evolve with wear. Gold itself doesn’t tarnish, but the alloys it’s mixed with can deepen or mellow in tone. This soft shift is part of what makes fine jewellery alive, a reflection of the life it accompanies.

If you prefer a high polish, a jeweller can re-buff or re-plate your piece occasionally; if you prefer patina, let it tell your story naturally.

How to Store Jewellery Safely

• Keep each piece in a soft pouch or separate box compartment.

• Avoid stacking gemstone rings together — harder stones can mark softer ones.

• Store away from heat and sunlight, especially for opal and emerald, which can be sensitive to dryness.

• Once or twice a year, give your collection a quiet afternoon of care — a ritual to reconnect with what you own.

What Makes Bianca Jones Jewellery Ethical?

Each piece is made in solid gold, using responsibly sourced materials and recycled metals wherever possible. Our gemstones are individually chosen for colour, character, and symbolic resonance, never mass-produced or lab-assembled. We believe transparency is the new luxury.

Your jewellery is made to last — but also to live. Caring for it isn’t about perfection; it’s about presence. Every polish, every quiet check of a clasp or gemstone, is an act of love for what you’ve built, worn, and become.
