The art of wood grain metal
The art of fusing precious metals into layered billets — each one a unique geological event in gold, silver and platinum.
The art of wood grain metal
Mokume-gane — 木目金 — translates literally as "wood grain metal". The technique was developed in 17th century Japan by master metalsmith Denbei Shoami, originally to decorate the fittings of samurai swords.
Thin sheets of contrasting metals — gold, silver, copper — were fused together under heat and pressure, then carved, rolled and worked to reveal the extraordinary wood-like grain patterns hidden within the layered billet.
For centuries the technique was practised by only a handful of master craftspeople. Today, Wabi Mokume is among an exceptionally small number of jewellers worldwide working with Mokume-gane at the highest material standard — using 18ct golds, platinum and palladium, from our studio in the Birmingham Jewellery Quarter.
Denbei Shoami develops the technique for sword fittings. The layered patterns were prized as symbols of nature and impermanence.
Following the abolition of the samurai class, Mokume-gane masters turn to decorative arts and jewellery, preserving the tradition.
Metalsmith Hiroko Sato Pijanowski introduces the technique to Western jewellers, sparking global interest.

The Mokume-gane process
From the raw precious metal sheets to the finished piece, every stage of the Mokume-gane process is carried out entirely by hand in our Birmingham atelier. There are no machines that can replicate this — only time, skill and fire.
Sheet preparation
Precious metal sheets are prepared, cleaned and polished to a mirror surface. Absolute purity of contact is essential; any contamination prevents fusion.
Billet construction
The sheets are stacked in a carefully chosen sequence — the order determines which patterns will emerge. The stack is compressed in a bespoke forge under extreme heat and pressure until the metals diffusion-bond at a molecular level.
Pattern revelation
The fused billet is worked — rolled, twisted, carved, chased and shaped. Each cut into the surface reveals a cross-section of the layers beneath, creating the extraordinary wood grain, wave and landscape patterns unique to this piece.
Forming & setting
Once the pattern is revealed, the Mokume-gane is formed into its final shape — ring shank, pendant form, earring drop — and gemstones are set by hand using traditional techniques that complement rather than compete with the metal.
Precious metals, chosen with intention
Every metal in a Wabi Mokume billet is chosen not only for its intrinsic quality, but for how it will behave in the fusion process — its colour, its hardness, and above all, the contrast it creates within the layers.
18ct Yellow Gold
Rich, warm, and timeless. The classic Mokume base.
18ct Rose Gold
Warmer and softer — rose gold creates intimate, romantic layering.
18ct White Gold
Cool and refined, white gold creates sharp tonal contrast.
Silver
Pure silver introduces brilliance and soft contrast.
Platinum
The rarest structural metal — dense, enduring, brilliantly white.
Palladium
Lighter than platinum, palladium creates delicate silver-white layers.
The same metals. Entirely different pieces.
Even when two rings are ordered with identical metal combinations, the pattern that emerges is never the same. The grain is determined by how the metalsmith works the billet, the sequence of the layers, the heat applied, and the natural variation in the metal itself. This is what makes each piece genuinely one of a kind — not a marketing claim, but a metallurgical fact.
"We can guide the direction of the pattern. We cannot predict exactly what will emerge. That is the nature of Mokume-gane."
Set entirely by hand
A Mokume-gane ring does not need a stone to be extraordinary — but when one is chosen, it is set entirely by hand using traditional techniques that complement rather than compete with the metal.
Sapphire
Deep blue — loyalty and wisdom.
Ruby
Vivid red — passion and devotion.
Emerald
Rich green — rebirth and love.
Diamond
Brilliance and endurance.
Alexandrite
Colour-shifting, rare and personal.
Morganite
Blush pink — warm and romantic.
We source stones individually for each commission. If you have a stone in mind — or an heirloom stone you'd like to incorporate — we'll discuss this during your consultation.
