EXPLORE EXPO CHAINS

Expo Chains was founded on a simple belief: premium jewelry shouldn't cost a fortune.

For too long, the choice was limited. Affordable pieces faded quickly, while high-quality jewelry came with an expensive price tag.

We wanted to create something different. Jewelry that looks refined, feels premium, and is built for everyday life. Pieces you can wear from morning to night, in the shower, at the gym, by the ocean, and everywhere in between, without worrying about tarnishing or losing their shine.

When we couldn't find it, we decided to create it ourselves.

Timeless designs. Durable materials. Made to be worn every day and backed by a lifetime warranty.

Frequently asked questions

Is your jewellery waterproof and sweatproof?

Yes. Every piece is made from 316L stainless steel and finished with PVD plating, so it's fully water and sweat resistant. Shower in it, train in it, wear it every day. It won't rust, tarnish, or turn your skin green.

What is your jewellery made of?

Premium 316L stainless steel, plated in 18K gold or rhodium using PVD (physical vapour deposition). PVD bonds the finish far thicker than standard plating, so the colour holds up to everyday wear.

How is it packaged?

Every order arrives gift-ready in protective Expo Chains packaging, ready to wear straight away or give as a gift.

Are duties and taxes included?

UK orders are all-inclusive. The price you see at checkout is the price you pay, with no surprise fees on delivery. International orders may be subject to local import duties depending on the destination.

Can I wear it in the pool or sea?

Yes. Our pieces are built to handle both chlorine and saltwater, so you can swim in the pool or the sea without losing the shine.

Do you offer a warranty?

Every piece is backed by our lifetime no-fade guarantee. If the colour ever fades, we'll replace it, just reach out with your order details.

Do you ship internationally?

Yes. We offer free UK shipping on orders over £60 (2 to 3 working days), and worldwide delivery is available. Shipping options and times are shown at checkout.
