The Stone

See the natural beauty of Pietra Grey up close — the surface texture, colour depth, and veining that make this quartz unique.

Colour:

Charcoal White Grey

Deep charcoal quartz with bold white diagonal veining — a striking, high-contrast dark marble surface.

Unistone Pietra Grey delivers one of the most dramatic designs in the entire Unistone range. Its deep charcoal grey base provides a sophisticated cool backdrop for bold, bright white veins that run predominantly diagonally, branching and intersecting to create a dynamic dramatic pattern. A dense network of much finer thread-like light grey veins fills the background, adding subtle depth and a cloudy textural quality. The polished finish amplifies the striking contrast between the deep charcoal and the bright white veining. Pietra Grey recreates the character of natural Pietra Grey marble from Iran — one of the world's most prestigious dark marbles. Manufactured by Brachot with Through Tone Technology. Over 90% natural quartz, NSF certified. 15-year warranty. Available in standard and jumbo slab formats. Supplied and installed by In2Stone across Hampshire.

Frequently Asked

Questions About Pietra Grey

What does Unistone Pietra Grey look like?
Pietra Grey has a deep charcoal grey base with bold, bright white diagonal veining that branches and intersects dynamically. A dense network of finer light grey veining adds cloudy depth to the background. The polished finish amplifies the high-contrast drama. It's one of the most striking, boldly dramatic designs in the Unistone range.
What is Pietra Grey marble?
Pietra Grey is a prestigious natural marble quarried in Iran, known for its deep grey base with striking white veining. It's one of the world's most sought-after dark marbles. Unistone Pietra Grey recreates this character using engineered quartz, delivering the same dramatic aesthetic with superior durability, stain resistance, and a 15-year warranty.
How does Pietra Grey compare to Cinza?
Both are dark marble designs with lighter veining, but at different intensity levels. Cinza has a charcoal base with delicate, fine web-like grey veining — subtle and sophisticated. Pietra Grey has bold, bright white veining that creates dramatic diagonal movement — striking and commanding. Cinza is understated dark marble; Pietra Grey is show-stopping.
What cabinetry suits Pietra Grey?
White or light grey cabinetry creates clean contrast that lets the dramatic worktop dominate. For a moody, enveloping scheme, dark cabinetry with Pietra Grey creates a dramatic, night-like kitchen. Brushed gold or brass hardware creates warm accents against the cool charcoal. Under-cabinet lighting is essential to showcase the bold white veining.
Does Through Tone Technology matter for Pietra Grey?
Absolutely — the bold white veining against the dark base makes exposed edges very noticeable. Through Tone Technology ensures the dramatic veining runs through the entire slab thickness. Waterfall island edges, mitred corners, and exposed ends all display the same striking white-on-charcoal marble character.
★★★★★
"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops. Well done to the entire team - you've exceeded my expectations!"
