Ring Necklaces

One Piece, Worn Two Ways

A spinner ring that doubles as a necklace. Every ring necklace carries a gearing, brass gear spinners on a steel ring, turning between two plates. Lift it off to wear on your finger, then put it back and it's a necklace again. The rest of the piece is the same stainless steel and brass as all our jewellery, sometimes with anodized aluminum.

The Maker

From the Artist Who Armours Mice

Jeff de Boer has spent more than 40 years making museum-quality suits of armour for cats and mice: thousands of pieces since his first armoured mouse in 1986, featured by National Geographic and NPR. He is a member of the Royal Canadian Academy of Arts, and makes everything from jewellery to large public sculpture. Every Armét piece is assembled by hand in his Calgary studio.

Coming Soon

Design Your Own, from the Plates Up

We're building a configurator where you choose the plates, the gears and the stones, and design a piece from nothing. Can't wait? Every piece already opens in 3D on its product page, where you can change nearly everything but the plates (the gears, their colours, the stones, even which way the plates face) and watch it update as you go.

The first Gearings

The idea began when Dylan Puddu brought the Gearing concept to Jeff de Boer and Dave Sangra. Together, they developed it and worked to get it manufactured.

A component design system

Edward Jaworenko joined Jeff de Boer to develop a modular system of jewellery components, opening up more choices of shape and design.

365 Days of Design

Our 365 Days of Design campaign explored combinations of gears and plates. That year also brought our first gallery placements at the Glenbow Museum and Bluerock Gallery.

More contributors and possibilities

Andrew Holloway joined the team and contributed to the jewellery. We explored hexagonal designs, planetary gears and bolo ties, and took our jewellery to the Calgary Stampede. Around this time, we also began thinking about an app for customers to explore designs.

Making it digital

Our jewellery was easier to show across a table than on a screen. We were working on ways to help people see its movement and explore the different designs online.

Cat and mouse armour in print

Late in 2022, National Geographic featured Jeff de Boer's cat and mouse armour.

A tariff rethink

Changes to US tariffs pushed us to reconsider how we sell and deliver our jewellery. That raised a broader question: how could we make it easier for people to discover Armét, understand the moving parts, and choose a piece of their own?

Preparing for launch

An earlier version of our app produced offline renders and had exactly one user: Edward. We're now preparing the experience we had in mind for customers: a way to explore and personalise our jewellery in 3D. The app and new website are still in development. We're working to bring that experience closer to choosing a piece at our table.
