The Stone

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

The most fearlessly dramatic surface in the Compac range — thick, sweeping black veining slashes across a bright white base with extraordinary contrast and power.

Unique Calacatta Black is the single most dramatic surface COMPAC produces. Thick, sweeping black veining flows diagonally across a bright white base with extreme contrast — large patches of deep black and dark charcoal carve bold rivers of darkness through the luminous white background, while fine grey threads extend from the main veins like smoke trails. Dense, concentrated black masses alternate with expansive clean white space, creating a visual rhythm that is both powerful and natural. This is a statement surface in the truest sense — every kitchen island, bathroom vanity, or feature wall that carries Calacatta Black becomes the absolute focal point of the room. The black-and-white contrast is timeless and versatile, working equally well in ultra-modern minimalist spaces and in classical high-ceiling interiors. Part of the COMPAC Unique collection, manufactured in Spain from 93-95% natural quartz crystals. Completely non-porous, NSF and Greenguard certified, with a 25-year residential warranty. The engineered composition means this bold pattern will never stain, never discolour, and never require sealing.

Frequently Asked

Questions About Unique Calacatta Black

What makes Unique Calacatta Black so dramatic?
Unique Calacatta Black is the most dramatic, highest-contrast surface in the entire Compac range. It features a bright white base with extremely bold, sweeping black veining — thick, confident strokes of deep black and dark charcoal flowing diagonally across the slab with fine grey threads extending from the main veins. The effect is breathtaking and unforgettable.
How does Unique Calacatta Black compare to Ice Max Black?
These two surfaces approach black-and-white contrast from opposite directions. Ice Max Black places white veining on a black base — the surface reads as a dark worktop with light accents. Unique Calacatta Black does the reverse — black veining on a white base — creating a bright surface with dramatic dark accents. The overall feel is completely different despite sharing the same colours.
Is Unique Calacatta Black suitable for a small kitchen?
While the veining is dramatically bold, the white base keeps the surface feeling bright and open. In a smaller kitchen, it works exceptionally well as a statement island or feature piece, balanced by simpler perimeter worktops. The key is to let Calacatta Black be the star — keep surrounding surfaces, cabinets, and walls restrained so the stone can speak.
What cabinet colours work with Unique Calacatta Black?
White or very pale grey cabinetry is the safest and most effective pairing, allowing maximum focus on the extraordinary veining. Dark cabinets can work in large, well-lit kitchens but risk competing with the stone's own dramatic darkness. Mid-tone grey creates a bridge between the black veining and white base. Brass or matt black hardware adds finishing elegance.
Is Unique Calacatta Black part of the premium Unique collection?
Yes. Unique Calacatta Black sits within Compac's premium Unique collection, which represents the pinnacle of Compac's marble-replication technology. The Unique collection focuses on achieving the most faithful, natural-looking interpretations of iconic Italian marbles, and Calacatta Black delivers the most dramatically contrasted example.
★★★★★
"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!"
