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.
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.
How it moves
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 gardener, the honey-on-everything friend, the one who stops for every bee. A plump bumblebee hangs from a heart full of petals and swings as you move, while two gears turn at the pace of a slow summer afternoon.

For the person who sees maths in everything, the ocean included. A small nautilus floats in a wide halo while a planetary gear train turns around it: sun, planets and ring, spiral growth and orbit in one piece.
