Brazilian exotic with bold horizontal grey-white wave veining across a deep charcoal-black polished base.
Sea Wave Cosmic granite is the polished sibling of Sea Wave Cosmic Caress, quarried from the same Brazilian geological formation but finished to a high-gloss polish that maximises the contrast between the dark base and luminous veining. The slab presents a deep charcoal-to-black base with prominent horizontal and undulating veining in pale grey-white and mid-grey, ranging from fine thread-like lines to broader wavy bands and splotchy formations. The lighter veins display a subtle granular texture and sparkling speckling, and the polished finish gives the entire surface a reflective depth.
Where Sea Wave Cosmic Caress incorporates a caressed finish element, the standard Sea Wave Cosmic commits fully to high-gloss polish. This choice amplifies the drama — the dark base becomes deeper and more mirror-like, the lighter veins become more luminous, and the sparkling crystalline inclusions catch light more intensely. The layered horizontal wave pattern creates a sense of geological movement that sweeps across the slab like ocean currents frozen in stone. Performance is standard Brazilian granite: Mohs 6–7 hardness, excellent heat resistance, and the dense igneous composition that ensures long-term durability.
In2Stone recommends Sea Wave Cosmic for clients who want maximum visual impact from a dark veined granite. The polished finish delivers the most dramatic expression of the wave pattern, making it ideal for feature islands and long worktop runs where reflective depth and sweeping movement can be fully appreciated. Pair with simple monochromatic cabinetry to let the stone command the room.

"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."— Nicky HavardGoogle Review
