Sustainability

What matters to ARCELF is sharing what we choose, who we work with, and how each piece is made.

Where the materials come from.
Whose hands they pass through, and where they take shape.

Being able to know the story behind what you wear — we believe this, too, is part of what it takes to choose something well.

Made in Japan

ARCELF jewelry is made in Japan, by Japanese workshops and artisans. From design and prototyping to casting, stone setting, polishing, and finishing — each piece takes shape through ongoing dialogue with the makers responsible for every step.

As a rule, our pieces are made to order, with production beginning only after your order is placed. Making what is needed, only in the amount that is needed. Holding as little excess inventory as possible is also part of how ARCELF chooses to make things.

Being Chosen Creates Continuity

Visiting workshops across Japan, we encountered both extraordinary skill and the difficulty of carrying it into the next era. Conveying the beauty of craft alone is not enough to keep that work alive — ARCELF begins from that question.

One collection, one craft. The founder visits each workshop herself, and through dialogue with the artisans, re-edits the techniques and landscapes passed down in each place into jewelry. Each stage of production is entrusted to artisans and workshops with the relevant expertise, and their work is paid for as such.

Returning value to craft is not limited to collaboration. While commissioning jewelry production creates work directly, we have also established a system of donating a portion of sales to workshops, so that value can reach those for whom collaboration is not a viable form. What we aim for is not one-time support, but a flow in which work and funds continue to circulate back to the makers, as pieces continue to be chosen.

Not merely "preserving" craft, but creating a cycle in which techniques are used, work is generated, and skills are passed on to the next generation — because people living today choose them. That is the future ARCELF works toward.

Where Our Materials Come From

We choose our materials not only for their beauty, but with thought given to where they come from and the background they carry.

METAL

The precious metals used in our pieces — Silver 925, K10, and K18 gold — are sourced through specialized suppliers in Japan and worked and produced in Japanese workshops.

LAB-GROWN DIAMONDS

The lab-grown diamonds used in our pieces are sourced through a specialized supplier in Japan. We have obtained a written declaration of origin and conflict-free status from our supplier, confirming that the diamonds were not manufactured, processed, or routed through the Russian Federation, and that they do not originate from conflict-affected regions.

GEMSTONES

Some of our pieces feature deadstock natural gemstones that have long been held in the market. Rather than presupposing new mining, we choose to find beautiful stones that already exist in this world and give each one a new role.

For this reason, the same color or shape of stone may never appear again. We treasure the individuality of each piece as part of the story its material carries.

SILK

Behind our first collection lies Nishijin tsumekaki hon-tsuzure weaving by Soshi Tsuzure-en in Nishijin, Kyoto — a tapestry weave in which the artisan files their own fingernails into a fine serrated edge and uses them to comb the threads into place, one by one. The layering of threads, the shifting of light, the scenes witnessed in the workshop — these are re-edited into jewelry.

Going forward, we are also considering giving new roles to materials that remain in the workshop, such as offcuts born from the weaving process.

URUSHI

Pieces featuring urushi lacquer are made together with Makino Shikkougei (Makino Urushi Studio) in Kyoto. We use genuine urushi. Rather than substituting the gloss of synthetic resin, we draw on the depth born of layering and polishing lacquer, and the expression that only handwork can bring.

How can a technique passed down over generations live within the small scale of jewelry? Through ongoing dialogue with the artisan, we give form to each piece, one at a time.

The Makers

An ARCELF piece is never completed by one pair of hands alone. The work of artisans who have inherited their skills in different regions comes together to form a single piece of jewelry.

Jewelry Production Kofu, Yamanashi / Tokyo

Centered on a workshop in Kofu — one of Japan's foremost jewelry-making regions — with certain processes carried out together with artisans and artists in Tokyo. Casting, stone setting, polishing, finishing: each piece takes shape through the hands of makers with their own specialized skills.

The People Who Carry the Craft

For the craft at the heart of each collection, ARCELF also values sharing who carries it, and the story behind it.

Soshi Tsuzure-en Nishijin, Kyoto

A workshop devoted to Nishijin tsumekaki hon-tsuzure weaving. The technique of filing one's own fingernails into a fine serrated edge to comb the threads into place, one by one — together with the scenes of thread and weaving witnessed in the workshop — became the origin of ARCELF's first collection.

Makino Shikkougei Kyoto

A workshop that carries on the art of urushi lacquering, working on temples and shrines among many other lacquer commissions. Together, we explore new expressions of urushi in jewelry, drawing on the luster and depth of the lacquer itself, and the character it develops over time.

On Wrapping

We also take care not to add more than is needed around the jewelry itself. The box is designed to stand as a gift on its own, and as a rule, we do not add further wrapping over it.

Paper invoices are, as a rule, not enclosed; the information you need is delivered digitally. Each is a small choice — but we begin by not adding what is not needed.
