Plain Polished Fine Grain

One of the world's purest black granites — quarried exclusively in Quebec, Canada by Polycor Inc. with over 150 years of heritage, naturally achieving its colour without enhancement.

Cambrian Black holds a singular position in the world of natural stone. Quarried exclusively from a single legendary quarry deep in Quebec's countryside by Polycor Inc., it is one of the few truly black granites in the world that achieves its colour naturally — without dye, resin, or any form of enhancement. The result is a surface of pure, absolute black with an exceptionally fine, uniform grain and virtually no visible mineral variation. It is the little black dress of the stone world — simple, perfect, and enduringly elegant. The purity of Cambrian Black extends beyond its colour. Its exceptionally low porosity makes it naturally resistant to staining, and its dense, fine-grained mineral structure produces a mirror-like polish of extraordinary quality. When you look at a polished Cambrian Black surface, you see genuine depth — a blackness that has dimension, reinforced by the knowledge that this colour is millions of years old and completely authentic. For homeowners who want the ultimate in dark stone purity, Cambrian Black is the definitive choice. There is no compromise, no variation, no distraction — just the purest black surface that nature can produce, quarried by masters who have been extracting it for over a century. It is the gold standard of black granite.

Frequently Asked

Questions About Cambrian Black

Is Cambrian Black granite enhanced or dyed to achieve its colour?
No — Cambrian Black is one of the few black granites in the world that achieves its deep, pure black colour entirely naturally. No dye, resin, or enhancement treatment is applied. The black colour comes from the stone's natural mineral composition, making it genuinely, permanently black through and through. This natural purity is one of its most prized and marketed qualities.
Why is Cambrian Black quarried exclusively by Polycor?
Polycor Inc. owns and operates the single quarry in Quebec, Canada that produces Cambrian Black. This exclusivity means Polycor controls the entire supply chain from extraction to distribution, ensuring consistent quality standards. The quarry has been operational for over a century, giving Polycor unmatched expertise in extracting and processing this specific stone. Single-quarry exclusivity also contributes to the stone's premium status.
How does Cambrian Black compare to other black granites?
Cambrian Black has the purest, most uniform black colour of any commercial granite — virtually no visible mineral variation. By comparison, Black Galaxy (India) has golden bronzite sparkle, Absolute Black (India) may have slight mineral variation, and Belfast Classic (South Africa) can show subtle grey undertones. Cambrian Black is the choice for those who want the absolute purest black with no distraction.
Does Cambrian Black granite show fingerprints?
On a polished surface, yes — like all dark, polished stones, fingerprints are more visible than on lighter surfaces. This is the one practical trade-off of pure black stone. For reduced fingerprint visibility, a honed or leathered finish is recommended. The honed finish maintains the black colour intensity while significantly reducing smudge visibility. In2stone can finish Cambrian Black in your preferred texture.
Is Cambrian Black granite suitable for commercial projects?
Cambrian Black is highly sought after for commercial and architectural projects — luxury hotel lobbies, corporate reception desks, restaurant bars, and high-end retail installations. Its pure black colour, exceptional consistency, and natural (unenhanced) purity make it a favourite with architects specifying premium materials. Polycor supplies in large commercial volumes as well as residential quantities.
★★★★★
"We decided to get bespoke granite work tops for our new kitchen and have to say that we are over the moon with them. From the outset, Ian was very professional when selecting the stone, he listened to what we wanted, went through all of the possibilities that we could have for our worktops and went through the process in detail once we had made a decision. The templateing and fitting was carried out by an incredibly professional and helpful team run by Kev, who knew exactly what they were doing and just got on and made my kitchen look amazing. I would highly recommend In2stone for a helpful, knowledgeable and professional service from start to finish."
