A small behind-the-scenes glimpse of the museum pieces we created for the Next Nature Museum.

We created 8 different jewelry pieces, each representing a different era in time.
In this post, we are highlighting these two.

MID 18th century
During this period, glass became an industrial material. It shifted from rare and handcrafted to functional.

In this piece, glass is combined with metal and hinges materials that together refer to movement, production, and mechanics.

Pre-18th century
These earrings are inspired by flint weapons and fossils.
We pressed fragmented metal elements into aluminum using a 60-ton press. Parts of the elements were intentionally left embedded in the aluminum, while others were removed.

This process creates a fossil-like effect: traces of material captured through pressure and time.

The final hours of Salone del Mobile have begun.

What a week.
We met beautiful people, moved through nights and parties, saw things that stayed with us, ate well, got inspired, and most of all, we enjoyed.

There’s something about a week likOrlandi how it connects, how paths cross, how things unfold. We love to be part of that.

You can find us in Milan at Rossana Orlandi.

It feels like things are starting to unfold, new opportunities keep finding their way to us, but we also return to what has been important from the beginning. This year, we’ll be presenting again at , for the fourth time. It’s a moment that means a lot to us, not only professionally but personally. Milan becomes a place where our worlds come together friends, family, and the creative field, all meeting in one city. It’s both inspiring and grounding.

If you’re in Milan, come by.

All the women behind Tweek-Eek !! ❤️❤️❤️

Tweek-Eek was founded by twin sisters Roos and Geertje Eek. Working together as twins is something unique; the collaboration is almost instinctive. A natural balance developed between us early on: where one gravitates away, the other steps in. This quiet division of roles has always been part of how we work. We are each other’s eyes and ears. It is exactly this dynamic that gives the company its strength. The longer we work together, the more we realize that our power lies in this interplay.

But Tweek-Eek is more than us.
Our mother plays an indispensable role within the company. The creative foundation was laid early on: our parents encouraged us to develop our own voice and signature. Today our mother is still closely involved. She thinks along about concepts, helps realize photoshoots, stands beside us at fairs, and always looks along with a critical and honest eye. That sharp, loving perspective is invaluable.

Our sister Lieve has also been part of the story from the beginning. She creates our campaign photography and works under the name Maria Bodil, where she develops her own distinctive projects. Her visual signature and her honest opinion have strongly shaped the identity of our brand.

And then there is our grandmother. She is the one who always connects and brings everyone together. And so much more ❤️

For Women’s Day we want to acknowledge the women who are part of the story behind Tweek-Eek, generations of women who shape the brand.

For the Evoluon museum ( ), we were commissioned to develop jewelry using materials from different time periods. The objects are large, raw, sometimes even unwearable. There was no “limited,” so we were free to push it further.

We worked, for example, with lava (basalt), glass, flint, and copper circuit boards, materials that all share the same origin: they ultimately come from the earth, formed through heat, pressure, cooling, and time.

We explored those same processes ourselves.

Using a 60-ton press, we pressed fragmented metal elements into aluminum. Some parts remained embedded, others were pulled back out, like exposing a fossil. Traces of material captured under pressure. In other cases, the force split the material apart, allowing it to take on a new form.

Thise process mirrors how we normally work. In our own collections, we also use leftover materials and industrial techniques to create something new. This time it wasn’t waste, but the principle remained the same: transformation through experimentation.

The earth has been doing this for centuries.

These are a few of the pieces, in total, we created eight. They can be viewed at

Discover a world where rigid metal transforms into fluid forms. A bold exploration of material and machine, Through twisting, bending, and pressing, we transformed metal into organic, almost fluid forms.

This year was shaped by positive movement. 
Step by step, we kept moving forward. With special moments along the way:
new connections, international steps, work welcomed into museums, and countless developments you don’t always see.

What all of this has been building toward will take shape in 2026. We’re looking forward to taking you along.

We wish you a beautiful start to the new year, filled with love, creativity, and positive turns ahead.

Grandmas are never too cheesy 😏

Our biggest supporter, together with our aunts and of course our mother.

Aunt Chantal has a large collection of Tweek-Eek jewelry.
She recently hid it because she went on holiday and then completely forgot where she put it. Oops. We’ll definitely spoil her extra this Christmas.

We already wish everyone a very warm Christmas. 💚
