Ceppo Grigio Oreo marble slab, honed, a cool grey conglomerate crowded with bold black-and-white clasts, suspended from a crane clamp in the Royal Stone yard in Los Angeles under a clear blue sky

Ceppo is the stone of fragments — a matrix in which whole pebbles and older stone are bound together over millions of years and then sawn flat. Ceppo Grigio Oreo is the coolest, boldest reading of that family: a soft grey ground crowded with large clasts that swing from bright chalk-white to deep charcoal, the high contrast that earns it the Oreo name. From across a room it reads as a lively grey terrazzo; up close it resolves into pebbles, shards, and the occasional palm-sized fragment caught mid-current and frozen.

These slabs are finished honed, which keeps the surface matte and architectural — no glare, no reflection — so the black-and-white clasts read as structure rather than shine. Where Ceppo Creme runs warm and calm and the Rosa runs rosy, Grigio Oreo sits firmly in the cool register: a confident grey field that pairs naturally with blackened steel, rift oak, and polished nickel.

From the slab arrival, June 2026

It works as a statement kitchen island, a powder-room surround, or a full feature wall where you want pattern and movement without warmth. The contrast carries at scale, so it holds its own on large continuous runs.

On display at the Royal Stone yard on Sepulveda. Come see it under daylight before it moves.
