London Grey Adamantium

The slab pattern is dominated by a dramatically dark, anthracite-grey-black ground tone run through by powerfully moving silver-cream and grey-white bands of movement. The veining reads as dynamically swirled, almost like a pattern of glacial meltwater streams or a black and silver cloud formation. In places the pale layers condense into powerful bands, then dissolve again into more finely branched structures — every slab pattern is a unique geological section through the original block. Accents in warm rust-brown or gold-honey tones can occur here and there and are the result of secondary iron oxide mineralisations along former fissures.

This dramatic character makes London Grey Adamantium an outspokenly powerful architectural material. In modern kitchens, demanding residential architecture, hospitality and commercial architecture the material develops a self-assured, urban atmosphere. Unlike monochrome black solid stones, London Grey Adamantium shows an architectural material history with a clearly recognisable axis of movement.

Technically, London Grey Adamantium is a robust high-performance dimension stone. Brazilian quartzites of this class typically show high compressive strength, low water absorption, complete acid resistance and frost resistance. The Mohs hardness of around 7 protects against scratches from steel knives and the usual kitchen tools — wine, lemon, tomato sauce and cola leave no etch marks. On heavily used kitchen worktops a single impregnation at installation makes sense, because dark quartzites can otherwise show slight saturation marks from oil or greasy foods on areas that are not impregnated.

The surface finishes available from stock are listed in the »Finishes« block further down. On request we produce from them kitchen worktops, islands, vanity tops, wall claddings, treads and risers, window sills, façade elements, pool surrounds and project-specific special cuts. For book-match compositions with mirrored slab sequences from adjacent blocks we are glad to reserve material directly from the same block on request.

For anyone comparing London Grey Adamantium with other materials: stylistically close are Cosmic Black (a Brazilian migmatite with a similarly dramatic black-and-light architecture), Patagonia (considerably lighter and with translucent quartz accents), Black Forest and Tiger Black (related Brazilian migmatites). Anyone looking for the same dark pattern of movement as a porcelain reproduction will find similar designs at Laminam Diamond Collection or Lioli Porcelain — with additional heat resistance in that case, but without the geologically authentic quartzite character.

Our honest assessment: London Grey Adamantium is a powerful choice for projects that want to set a striking accent with a dark quartzite look and an expressive dramaturgy of movement — with the full robustness of a high-performance hard rock. Anyone who needs a calm, monochrome black surface should reach for a classic black gabbro. But anyone who wants the dramatically dark quartzite image with the liveliness of silver-cream vein courses gets an exceptionally characterful stone in London Grey Adamantium.
