Our rituals

Each piece of jewelry
is a story.

At Aeterna, every piece of jewelry is much more than just an accessory. It is a ritual, a moment of connection, a celebration of your most cherished bonds.

The story

Because some things deserve
not to disappear.

Behind every piece of soldered jewellery lies a true story. A bond, a journey, a promise, a moment we never want to lose. Our role isn’t to sell an accessory — it’s to turn a precious moment into something lasting.

In short

Permanent jewellery,
in Brussels.

What it actually is

A fine chain, fitted to your wrist, your ankle or your neck, then welded shut on itself. No clasp: nothing to open, nothing to lose. You keep it in the shower, in the sea, at the gym. It lives with you, and it ages with you.

How a fitting works

Fittings are by appointment, in our studio on Rue du Marché aux Herbes, a minute from the Grand-Place. Allow 20 to 30 minutes: choosing your chain from around twenty styles, sizing it, welding it, adding the charms that suit you.

Three metals, three budgets

Stainless steel from €45, 925 silver from €55, gold-filled from €65. All hypoallergenic, all resistant to water, salt and chlorine. A €20 deposit confirms your slot and comes off the total.

If you change your mind

A pair of nail scissors is enough — painless, two seconds. Plenty of people come back to have the same chain welded again, from €5. Our pieces carry a 6-month warranty against tarnishing and weld failure.
