The Diamond Selection
A tenmoku-style glaze fired dark to the foot and breaking into fine amber streaks at the rim, the way iron pulls to the surface in a wood-fired kiln. Single-fired for the Diamond range, it costs less and still carries real depth.

The glaze
Amber streak · russet · dark umber · charcoal · near-black
One dark glaze, fired hot enough that iron in the mix migrates to the surface and pulls into fine streaks as it cools — the same "hare's fur" effect prized in old tenmoku ware, here on a single firing rather than two. The streaking runs thickest at the rim and thins toward the well, so the darkest part of every piece is its centre.
It is a rugged glaze rather than a delicate one: forgiving of stacking, resistant to scratching, priced for volume use. The amber never repeats in exactly the same pattern from piece to piece.

On the plate
Raw fish and seared red meat both read clean against the dark glaze, and the amber streaking picks up any golden crust or citrus zest without help.
Pale proteins and bright garnish colours carry hardest: tuna, scallop, egg yolk, pea green, chilli red. Dark sauces need a glossy finish to separate from the glaze.
A workhorse finish for high-volume service — sushi counters, tasting menus, small plates. Handles daily stacking and scratching better than the double-fired ranges.
In service
Short enough to hand to a section chef.

On the square plate
300g wagyu striploin · 2 radishes, sliced thin · 100ml beef jus or reduced stock · flaked salt · black pepper · neutral oil
Pink beef against near-black is the highest-contrast pairing this glaze offers, and the amber streaking at the rim echoes the seared crust.

On the compartment tray
180g sushi rice, seasoned · tuna, salmon and eel (or your choice of three), sliced for nigiri · nori strip · soy sauce · wasabi · pickled ginger
The tray's built-in compartments do the mise en place for the server, and the amber streak under the soy well doubles as a visual guide.
