Aethertek

From the workshop

Hand-woven in small batches. Each piece signed by the maker.

Hand-wound · Copper-laced

The geometry
of grounding,
worn close.

A toroid hand-woven from waxed black cord, threaded with a lattice of pure copper filament. Weighted. Quiet. Conductive. Made to be worn for a decade, not a season.

— The Object

Carved from shadow,
threaded with light.

Photographed in the studio, unedited. What you see is what arrives — a single, signed object with no two latticeworks identical.

— Why it earns its place

Six reasons it stays
around your neck.

01

A weighted center

The toroid is dense by design. You feel its resting place against the sternum — a quiet, steady cue to soften the shoulders and find the breath.

02

Conductive lattice

A continuous plasmid of stillness — 99.9% pure copper, hand-wound through the form and brought into contact with the skin.

03

Passive harmonization

Copper's natural electromagnetic properties have been studied for over a century. The toroidal form invites a closed-loop field — a quiet counterweight to your day.

04

Hand-woven, hour by hour

Four to six hours of work per piece, hand-wound copper wire by copper wire — no machines. Every cross-thread is tightened, sealed in polyurethane, and inspected under raking light.

05

Adjustable cord, braided copper

A braided closure paired with a genuine amethyst focal and a carnelian lock bead. Slides freely, holds firm. Wear it at the collarbone, mid-chest, or low under a shirt. Yours to set.

06

Made for any neck

No clasp, no gender, no era. The toroid sits comfortably on broad and slender frames alike — meant to be lived in, not displayed.

— Craft & Material

What it's made of,
down to the gram.

Detail of the copper filament lattice on the woven black cord

  • Cord

    3 mm round leather necklace

    Supple round leather, soft to the skin and weather-stable, ageing to a deep matte black.

    3 in

  • Filament

    99.9% pure copper, 0.3 mm

    Hand-wound, copper wire by copper wire, in a continuous unbroken path. Drawn from a single source in northern Chile and annealed for softness before it ever meets the cord.

    6–10 g

  • Closure

    Amethyst focal · carnelian lock

    A genuine amethyst focal jewel sits at the throat as the centerpiece, with a smaller carnelian bead set lower to lock the slide and hold your chosen length. The braided closure adjusts 18" to 32" — no clasp to break, no metal at the nape.

    amethyst + carnelian

  • Form

    2.6″ outer · 0.9″ thickness

    Woven outward in twelve concentric passes, sealed in polyurethane, then finished a second time. Each piece tested for symmetry before it leaves the bench.

    28 g total

  • Time

    4–6 hours of human work

    Two artisans, no machinery. Each piece is hand-signed and accompanied by a business card noting the date it left the bench.

"If you're going to wear something every day, it should be the best thing in your drawer."

— The toroid

A shape that
returns to itself.

The toroid — the geometric form of a donut — is one of the few shapes in nature where energy that leaves a point eventually returns to it. It is the form of the Earth's magnetic field, of a smoke ring, of the cardiac muscle's electrical pulse.

For thousands of years, the toroid has been drawn into temple architecture, woven into talismans, and inscribed onto stone in cultures that had no contact with one another. The reason is not mystical — or rather, the mysticism is downstream of the physics. A closed-loop field is the most stable arrangement energy can take, and the human nervous system, like the Earth, is built to recognize it.

To wear a toroid is not to wear a symbol of grounding. It is to carry the geometry itself, in copper and cord, against the chest.

— The evidence

Read the science
for yourself.

We don't ask you to take our word for it. Below are independent, peer-reviewed studies on the principles Aethertek is built on — copper's properties and conductive contact with the body. Each opens the full paper. They examine the underlying science, not this specific pendant.

Appl. & Environ. Microbiology · 2011 Peer-reviewed

Metallic Copper as an Antimicrobial Surface

Bacteria, yeasts, and viruses are rapidly inactivated on contact with metallic copper — a phenomenon researchers call "contact killing."
