Negresco is the dark architectural anchor of the Antolini quartzite program. The field reads as graphite — a deep, cool charcoal that sits between black and slate — broken by a quiet network of fine white quartz veining and the occasional cooler grey cloud. There is nothing decorative about it; the slab is built to do the same job for a room that a blackened steel hearth or a board-formed concrete wall does, with the geological depth marble cannot deliver in this colour.

This lot is AO630, 2cm gauge, honed, measuring 78″ × 124″ — a wide working size for monolithic kitchen islands, full-height fireplace walls, bookmatched powder rooms, and bath floors where the matte surface is critical. Honed is the right finish for Negresco: a polish on this stone reads almost mirrored and loses the depth; honed keeps the graphite quiet and the white vein as drawing rather than reflection.

Pairs naturally with warm woods — walnut, fumed oak, smoked cherry — and with brushed bronze, antique brass, and unlacquered fittings that will warm against the cool field over time. Part of a new shipment of honed Antolini quartzite slabs that landed this week.

The slab is on the floor at 2303 South Sepulveda. Walk it in daylight against the yard wall and tag the piece that fits your project.
