Antolini Negresco · Block AO630 — Honed, in Los Angeles

Block AO630

The dark contemporary quartzite.

Quarried in Brazil and selected through the Antolini Negresco program.

Negresco is the dark contemporary register of Brazilian quartzite — a near-black field with cloud-like gray and silver movement drawn across. The Antolini Negresco program pulls the family’s cleanest and most contemporary register: the field reads even, the silver movement runs across the slab as atmosphere rather than ornament. The block is meant to be the room.

At 78″ × 124″, Block AO630 sizes for focal kitchen islands, full-height bath walls, fireplace surrounds, and bar fronts. Honed keeps the dark register matte and architectural — polished would push it toward mirror and the cloud movements would compete with reflection.

The right Negresco for the room where the slab is meant to be the focal point. Pair with light oak, brushed brass, lime plaster, and a quiet Calacatta elsewhere in the house as the counterpoint. Runs beautifully as a contemporary kitchen island, a primary bath, a powder room, a fireplace surround, and a bar front.

One Finish · Honed

Honed,
to keep Negresco matte and architectural.

Block AO630 ships honed. The dark register is calibrated to a matte, contemporary surface — polished would push the cloud movements into spectacle and lose the architectural register. Honed forgives everyday etching and lets the slab read confidently against contemporary interiors.

The right surface for contemporary kitchen islands, primary baths, fireplace surrounds, and any application where the slab is meant to read as dark material.

2cm · 78″ × 124″ · Honed

Dark quartzite, matte, contemporary

Honing keeps the Negresco dark register confident and the silver movement quiet. The slab sits calmly against light oak, brushed brass, and lime plaster — and any patina that develops reads as part of the cloud register rather than wear.

Common Questions

Questions,answered.

What is Antolini Negresco quartzite?
Negresco is the dark contemporary register of Brazilian quartzite — a near-black field with cloud-like gray and silver movement drawn across. The Antolini program pulls the cleanest and most architectural register, the slab meant to be the room rather than ornament. Block AO630 ships at 2cm honed, 78″ × 124″.
Is Block AO630 available in polished or leather?
By special order. The slab ships honed, calibrated to keep the dark register matte and contemporary. Polished would push the cloud movements into spectacle; leather would soften the dark register. Bring drawings and we will lay the options against the honed lot on the floor.
Where does Negresco work best?
In the room where the slab is meant to be the focal point. A contemporary kitchen island, a powder room, a primary bath composed entirely of stone, a fireplace surround, a bar front. Pair with light oak, brushed brass, lime plaster, a quiet Calacatta elsewhere as the counterpoint.
How is Negresco different from Cristallo Nero or Bohemian Carbon?
Three different dark quartzite registers. Negresco reads as cloud-like gray and silver on near-black. Cristallo Nero reads as crystalline black silk. Bohemian Carbon reads as smoky gray velvet. Pick the register that fits the room.
Can Block AO630 be bookmatched?
Bookmatched Negresco is available on selected blocks. The slab ships as a single piece; matched pairs and matched sets are quote-on-request.
How do I see Block AO630 in person?
Royal Stone is at 2303 South Sepulveda Boulevard, West Los Angeles. Designers and private clients are welcome by appointment Monday through Friday. Call (310) 477-3223 and we will pull the slab for you.

Negresco reads more confident in person than in any photograph — the dark register is meant to live with contemporary architecture. We’d rather pull the slab and walk you through than describe it.
