About Fusion Crystal
Fusion Crystal lives from contrast: deep black ground areas are crossed by crystal-white quartz bands, and between them flash copper-red, ochre-brown and gold-glimmering accents. The slab image is not restrained — it carries rooms, and as a bookmatch or in island format it is an architectural element in its own right. Anyone looking for a quiet background surface is better served by other materials. Anyone who wants an expressive, almost geological spectacle will find a rare combination here.
Geologically, Fusion Crystal is a metamorphic quartzite from Brazilian deposits, predominantly from the state of Bahia. Quartzites form when quartz-rich sandstones are altered over millions of years under high pressure and temperature within the Earth's crust — quartz grains fuse into a dense fabric, and embedded iron and metal minerals provide the colour accents. With a Mohs hardness of about 7, the material is among the hardest in the range.
Technically, Fusion Crystal benefits from its quartz-dominated mineralogy: acids from wine, lemon, vinegar or coffee leave no etch marks on the polished surface. Water absorption is low, the material is frost-resistant and, in most configurations, suitable for external use. Compressive and flexural strength lie in the upper range of the natural stone scale — a property that makes quartzite worktops a resilient choice in kitchen and bathroom.
ROSSITTIS carries Fusion Crystal as a raw slab for kitchen worktops and vanity tops, in tiles for large-format floor and wall surfaces, as treads and risers and as project-specific cut-to-size. The choice of finish is decided by the desired effect: polished emphasises the crystalline depth of the white quartz bands most intensely and is the classic choice for prestigious bookmatch applications. The surface finishes currently in stock are listed in the »Finishes« block further down.
Compared with black marbles such as Nero Marquina or the Marquina variants, Fusion Crystal brings markedly more load-bearing capacity with it without giving up the theatrical look. Set against technical alternatives made from engineered quartz or ceramic, it remains a genuine natural stone with an individual slab image that can never be repeated. For projects that want to combine a narrative, expressive stone with full quartzite hardness, Fusion Crystal is a very coherent answer.
As a quartzite, Fusion Crystal is considerably easier to care for than most marbles. The polished surface tolerates acids from wine, lemon, vinegar or coffee without etch marks — that is the decisive difference from lime-bound stones. Even so, for kitchen worktops and vanity units we recommend a one-off silane- or polysiloxane-based sealer, because it prevents oil- and grease-type soiling from penetrating and so makes everyday cleaning easier.
For daily cleaning, clear warm water and a soft microfibre cloth are enough. For heavier soiling, use a pH-neutral natural stone cleaner; acidic or strongly alkaline household cleaners are not necessary and can attack the sealer if used frequently. Hot pots and pans can be set down directly, because quartzite is heat-resistant — trivets are sensible in order to avoid local stresses, but they are not compulsory.
Outdoors, Fusion Crystal remains frost-proof when correctly laid to a fall. Rinse off dirt from pollen, leaves or road salt with clear water in spring; a stone cleaner once or twice a year is enough. Sealing outdoors is not obligatory, but it can protect the copper-red and ochre accents against premature leaching.
Frequently asked questions
Is Fusion Crystal suitable for the kitchen?
Yes. As a quartzite, Fusion Crystal is acid-resistant and very hard (Mohs ~7) — wine, lemon, vinegar or coffee leave no etch marks on the polished surface. A one-off sealer gives additional protection against oil- and grease-type soiling.
Which finishes are available for Fusion Crystal?
The surface finishes currently in stock are listed in the »Finishes« block on this page.
Where does Fusion Crystal come from?
Fusion Crystal comes from Brazilian deposits, predominantly from Bahia. Characteristic is the combination of a deep black ground, crystal-white quartz bands and copper-red mineral inclusions — the result of metamorphic transformation over millions of years.
How do I clean and care for Fusion Crystal?
Daily cleaning with clear water and a microfibre cloth is sufficient. For heavier soiling, use a pH-neutral natural stone cleaner. A one-off silane-based sealer makes care easier in the kitchen and bathroom.
Is Fusion Crystal frost-resistant and suitable for outdoor use?
Yes. The low water absorption and the dense quartzite fabric make the material frost-proof when correctly laid to a fall. For heavily frequented external surfaces we recommend a matt, textured finish — it offers more slip resistance than polished.
Fusion Crystal or Nero Marquina — which fits better?
Fusion Crystal brings markedly more robustness with it than a classic Nero Marquina limestone: acid-resistant, twice as hard at Mohs ~7 and fully suited to kitchen use. Nero Marquina appears more restrained and cooler. Fusion Crystal is the choice when drama and load-bearing capacity are meant to come together.
