Ocean Blue is a blue-grey banded quartzite from Brazil with a striking, directional figure. It is suited to high-quality floor surfaces, stairs, façades and worktops wherever a technically hard-wearing stone with movement in the image is called for.

About Ocean Blue
Ocean Blue reads like a stone drawn in long lines. The blue-grey and dark grey bands run directionally through the slab and give the material a clear grain direction that appears distinctly architectural across large surfaces. The finishes currently available from stock are listed in the »Finishes« block further down this page. At ROSSITTIS we carry Ocean Blue for projects in which not only colour but also structure and direction play a part in the design.
Geologically, Ocean Blue is a Precambrian quartzite from Brazil, from the state of Bahia. The directional banding goes back to the metamorphic overprinting of an original sandstone: under pressure and temperature the quartz grains were welded into a very dense, hard fabric. It is precisely this mixture of mineral hardness and lively banding that makes the stone interesting: it appears more valuable than a uniform dark stone, yet remains more hard-wearing than many decorative marbles.
Technically, Ocean Blue belongs to the robust class. The bulk density lies at around 2,720 kg/m³, the water absorption at a very low 0.13 % and the compressive strength at about 201 MPa. Added to this is a flexural strength of around 9.8 MPa. In practice this means: the stone is frost-resistant, suitable for internal and external applications and also sensible wherever mechanical loading plays a part. Against household acid exposure it is markedly less sensitive than limestone or marble.
At ROSSITTIS, Ocean Blue is available as a raw slab, in tiles, as treads and risers, window sills, skirtings and as a kitchen worktop. It works particularly well on floors, stairs, wall claddings, façades and monolithic components. Because of the directional structure, the material should always be planned with a clean laying direction; processed as a mirrored pattern it can appear very elegant, laid without coordination it quickly becomes restless.
Our frank assessment: Ocean Blue is not a neutral all-rounder. Anyone expecting a completely calm, clouded blue surface is better served by a more homogeneous material. If, however, you are looking for a hard-wearing natural stone with a clear direction, cool colouring and a distinct character of its own, Ocean Blue is a strong choice.

Finishes
Ocean Blue is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Polished
Polishing is the most classic finish for quartzite — a glossy surface with the highest possible colour intensity and a pronounced sense of depth. Depending on the mineral composition, the effect can be satin-gloss in places. As a silicate rock it is fully acid-resistant and scratch-hard — ideal for kitchen worktops and feature surfaces.
Care & fabrication
Ocean Blue can be cleaned and cared for without complication in everyday use. For kitchens, bathrooms and heavily used floor surfaces we recommend a sealing treatment, even though water absorption is low. Clean with pH-neutral stone cleaners and little surfactant. You should avoid strongly acidic cleaners, aggressive descalers and permanently standing soiling in joints or on honed surfaces.
Frequently asked questions
Is Ocean Blue suitable for kitchen worktops?
Yes, Ocean Blue is well suited to kitchen worktops. The low water absorption and the high compressive strength speak in favour of hard-wearing use. A good sealing treatment, a clean substructure and the usual protection against impact loading at the edges remain sensible.
Is Ocean Blue really a quartzite?
Yes. Ocean Blue is a quartzite — a metamorphically consolidated sandstone whose quartz grains were welded into a very dense fabric under pressure and temperature. That is where its hardness and resistance come from, and what makes it suitable for heavily used floors, stairs and worktops.
Where does Ocean Blue come from?
Ocean Blue comes from Brazil, from the state of Bahia. The material is a Precambrian quartzite with a distinctive, directional banding.
Is Ocean Blue frost-proof?
Yes, Ocean Blue is regarded as frost-resistant and can therefore also be used outdoors. The precondition, as always, is proper construction, appropriate drainage and the right choice of finish.
How do I care for Ocean Blue correctly?
Clean the stone with pH-neutral natural stone cleaners and renew the sealing on treated surfaces at sensible intervals. Avoid aggressive acids and strongly alkaline cleaners, even though Ocean Blue is less sensitive than lime-bound rocks.
Ocean Blue or a uniform dark granite?
Ocean Blue is the better choice if you are looking for movement, direction and a play of colour. A homogeneous dark granite appears calmer and more technical. Ocean Blue, by contrast, lives precisely from its banded structure.
What does Ocean Blue cost?
The price depends on the batch, thickness, surface finish and fabrication — with natural stone there is no serious flat rate per square metre. Business customers see prices once their B2B account is activated; private customers receive a complete quote through a fabricator near them.
