Armet is now the exclusive place to purchase the ultimate in fine art jewellery: mouse armour pendants and earrings by Jeff de Boer. Inspired by his world-famous armour for mice, these 2.5-inch miniature versions are completely hand fabricated in Jeff’s studio and are each individually signed.
These pendants are handmade by Jeff himself in the shop. They are also made to order so we can't ship them out immediately. Expect upwards of 2 weeks to get them manufactured, then we will let you know when they ship!
They are available in polished silver and polished or brushed brass. You have the option to purchase a fine stainless steel chain in any custom length.
The Gearing is a unique spinner ring. You can wear it alone, or use it as a component in a larger piece of jewellery to work a mechanism. This versatility drove all of the First Edition ideas for Armet jewellery, and we continue to use it in some of the newer pieces as well.
The History
Where it all began. When Dylan Puddu approached Jeff de Boer and Dave Sangra they began developing and manufacturing the Gearing based on a hand-built prototype by Dylan.
Will it fit?
To add ease to buying Gearings, we have supplied the inner diameter of the rings here as an aid to what the sizes represent. Why? Throughout the world, there actually isn't a single consistent sizing chart that everyone follows, so the real dimensions should clarify what we are offering (particularly if you have a means of measuring your fingers or rings you currently have, such as a set of calipers).
The width of the rings are 5.5mm.
Inner Diameter in mm:
Size 6: 16.65mm
Size 7: 17.25mm
Size 10: 19.6mm
Size 11: 20.4mm
Size 14: 23.1mm
For the friend who stops for every bee. A plump bumblebee seen from above, wings curled around a striped body. Alberta makes more honey than any other province, and this one never stops working.

You collect what the sea gives back. A chambered nautilus rests in a smooth teardrop loop, cradled the way a find sits in the hollow of a cove, with a stone catching the light at its heart.
How it moves
It carries two working gears that interlock and turn together under a fingertip, not on their own. Cut to precise tolerances, with the quiet satisfaction of winding a mechanical watch.

You love winter, quietly, from somewhere warm. A long, slim drop, like an icicle hanging from the eaves under a street lamp, small enough to wear all season.

For anyone with a little Celtic in the family tree. A harvest wreath in openwork, braided like the last sheaf of the field and hung over the door for luck, with a ring at its heart that turns, then lifts off to wear on your finger.
How it moves
Its Gearing ring spins under a fingertip, and lifts off to wear on your finger while the pendant stays on. It carries one working gear that turns under a fingertip, not on its own. Cut to precise tolerances, with the quiet satisfaction of winding a mechanical watch.

For the hand that's always looking for something to do. Small enough to pass for an ordinary pendant, it sits there whenever your thumb goes looking. Nobody else needs to know.

Taking what we learned from the A-Type pendant, the B-Type was born. The key difference between these two is that the back-plate is made of a single laser-cut piece of steel in the B-Type. The two pieces are riveted together in the A-Type. This is still our classic design.
Price is without gemstones. All Gearing Pendants come with a Gearing.
Pendant Size 7: 30mm x 43mm
Pendant Size 11: 31mm x 48mm
Note: These sizes are for the pendants without Gearings, which would add a few mm to the width and length.

You're the one who turns over rocks at low tide. Two shells from the same pool, the golden ratio twice over, with gears that roll under a thumb, catch, and roll again. Nature did the hard part; we just added the moving bits.
