Eclipse

Eclipse is a dramatically striped Brazilian quartzite migmatite with iconic storm veining – traded in the international stone trade as “Eclipse Quartzite” or “Black & White Storm”. The slab shows a vividly animated alternation of black and deep grey bands with light grey-white lightenings that sweep across the slab like a turbulent storm sky or a slowly flowing stream of water. At ROSSITTIS we fabricate Eclipse into statement kitchen worktops with book-matching potential, islands, bar counters, prestige wall claddings, dining tables and bathroom fit-outs with a dramatic, natural stone effect.

Petrographisch ein Quarzit-Migmatit – ein hochgradig metamorphes Silikat-Gestein mit charakteristischer schwarz-weißer Bänderungs­struktur (Foliation). Die Lagerstätten liegen im präkambrischen Schild Brasiliens (Bahia, Minas Gerais). „Eclipse" ist ein internationaler Handels­name für brasilianische Premium-Naturstein-Sortierungen mit dramatischer schwarz-weißer Sturm-Optik – verwandte Sortierungen werden auch als „Black & White Storm", „Storm" oder „Bianco Antico Storm" gehandelt. Im internationalen Stein­handel wird die Sortierung als „Quartzite" geführt – das ist durch den hohen Quarz­anteil und das säure­feste Mineralprofil gerechtfertigt.

About Eclipse

Background. “Eclipse” is an international trade name awarded by various Brazilian quarry operators to high-quality metamorphic natural stone grades with a dramatic black-and-white banded look. The batch carried in the ROSSITTIS warehouse shows the classic appearance of a Brazilian quartzite migmatite with pronounced foliation banding – a grade from the premium segment of Brazilian statement stones. Related grades with similarly dramatic black-and-white movement are also traded as “Black & White Storm”, “Storm”, “Black Forest” or “Bianco Antico Storm”. The grade belongs to the family of animated Brazilian premium quartzites and has been in international demand since the 2010s.

Finishes

Eclipse is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Poliert

Politur ist die klassischste Veredelung im Hartgesteinsegment — eine spiegelglatte, hochglänzende Oberfläche mit höchstmöglicher Farbintensität und maximaler Tiefenwirkung der Mineralstruktur. Als säurebeständiges Silikatgestein ist polierter Granit pflegeleicht und für Küchenarbeitsplatten, Wandverkleidungen und repräsentative Sichtflächen erste Wahl.

Satiniert

Die satinierte Oberfläche entsteht durch Bürsten, das weichere Minerale gezielt entfernt und der Fläche eine leichte Tiefe gibt. Mattes Erscheinungsbild mit subtiler Lichtreflexion und haptisch warmer Wirkung. Pflegeleicht, kratzunempfindlich und alltagstauglich — beliebte Alternative zur Politur in modernen Küchen und Wohnräumen.

Poliert RS satiniert

Beidseitig einsetzbare Platte: polierte Sichtseite mit höchstmöglicher Farbintensität und Spiegelglanz, Rückseite satiniert (gebürstet) mit matter, taktil warmer Anmutung. Eine flexible Konstruktion für Anwendungen, in denen Glanz- und Mattseiten je nach Einbauumgebung gewünscht sind.

Care & fabrication

Cleaning. In everyday use, warm water, a soft cloth or a clean mop and a pH-neutral natural stone cleaner are sufficient. Mild all-purpose cleaners, mild washing-up foam and all commercially available bathroom and kitchen cleaners are suitable. Take up spilled liquids promptly – the material is acid-proof, but on the polished surface dried droplets with dark pigment (coffee, red wine, black tea) remain behind as visible films.

Do not use. Strongly acidic special cleaners (HF-containing wheel cleaners, industrial glass cleaners), aggressive scouring sponges or abrasive pastes. Even though quartzite is chemically extremely resistant, scratching cleaning products can scour the polished surface matt.

Sealing. Recommended, but not obligatory. Eclipse has a water absorption of 0.1 – 0.3 % and is dense in itself. A premium sealer with silane-/siloxane-based stone protection makes handling grease, oil, wine and coffee easier on kitchen worktops – pigment uptake is reduced and cleaning is simplified. With strongly mineral-rich water, sealing is particularly advisable, because the pale areas of the slab are more prone to visible limescale films.

Kitchen and bathroom. In kitchen and bathroom use it is technically exceptionally robust: hot pots can be set down directly on the untreated slab for a short time – on sealed surfaces we nevertheless recommend a trivet, because very high temperatures can locally break down the sealer. Acids such as vinegar, wine, lemon and tomato leave no traces; anti-limescale sprays and all commercially available bathroom cleaners are approved. With Mohs 6 – 7, quartzite is one of the most scratch-resistant natural materials.

Book-matching and statement applications. Eclipse is frequently used in book-matched mirroring – the fluid storm movement of the veining produces impressive V-, X- or quad book-match patterns. We recommend planning the slab layout before installation with our stone engineering service.

Dramatic black-and-white slabs – special care notes. On a black-and-white striped natural stone slab, wiping marks show up in the pale bands as light films and in the dark bands as dark shadows – the differing tonality of the bands can make wiping routines visually challenging. On dark kitchen worktops, a consistent follow-up wiping routine with a soft microfibre cloth is advisable.

Floor and stairs. Outstandingly suitable as an interior floor in prestige areas. The finishes available from stock are listed in the »Finishes« block further down this page.

Outdoors and frost. Fully suitable. The finishes available from stock are listed in the »Finishes« block further down this page.

Scratches and repair. With Mohs 6 – 7, quartzite is extremely scratch-resistant. Deeper damage or dull patches on polished slabs can be locally reworked by re-polishing with diamond pastes – this work belongs in the hands of a specialised stonemason or joint-technology firm. Eclipse should be seen as a high-quality statement stone with individual batch selection – every slab is unique.

Frequently asked questions

What kind of material is Eclipse?

Petrographically a quartzite migmatite – a high-grade metamorphic silicate rock formed by pressure and heat deep in the earth's crust from an originally sandstone-like or migmatitic parent rock. The characteristic black-and-white banded structure arises from metamorphic mineral alignment – pale quartz-rich layers alternate with dark biotite- and amphibole-rich layers. The deposits lie in the Precambrian shield of Brazil (Bahia, Minas Gerais).

What does the name “Eclipse” refer to?

“Eclipse” is an international trade name awarded by various Brazilian quarry operators to premium natural stone grades with a dramatic black-and-white banded look. Related grades with similarly dramatic movement are also traded as “Black & White Storm”, “Storm”, “Black Forest” or “Bianco Antico Storm”. The name refers to the iconic storm look with its eclipse-like black-and-white drama.

What exactly does Eclipse look like?

A dramatic alternation of deep black-anthracite bands and light grey-creamy-white lightenings, crossed by powerful fluid vein courses in an irregular horizontal-diagonal distribution. The movement of the veining recalls a turbulent storm sky or a flowing stream of water – flowing and naturalistic rather than strictly linear.

What technical values does Eclipse have?

Values typical of Brazilian quartzite migmatites: bulk density 2,650 – 2,750 kg/m³, compressive strength 200 – 280 MPa, flexural strength 15 – 25 MPa, water absorption 0.1 – 0.3 %, Mohs hardness about 6 – 7. Frost- and de-icing-salt-resistant, UV-stable, acid-proof, heat-resistant.

Is Eclipse suitable for a kitchen?

Yes, outstandingly. As a quartzite migmatite, Eclipse is fully acid-proof (wine, vinegar, lemon and tomato leave no etch marks) and, with Mohs 6 – 7, one of the most scratch-resistant natural materials. Optimally suited to heavily used kitchen worktops and islands. A premium sealer is advisable, because the pale areas of the slab are more prone to visible pigment traces.

Is Eclipse suitable for book-matched installations?

Yes, outstandingly. The fluid storm veining can be composed by mirroring adjacent slab pieces into impressive V-, X- or quad book-match patterns – the grade is one of the strongest book-matching grades in its family. We recommend planning the slab layout before installation with our stone engineering service.

Eclipse or Patagonia?

Both are dramatic Brazilian premium natural stone grades with a dramatic clast texture. Eclipse shows classic black-and-white storm banding without golden accents; Patagonia additionally brings partly golden-yellow veins and clasts into the composition. The choice is a matter of style between classic black-and-white storm drama (Eclipse) and the more colour-versatile Patagonia appearance (Patagonia).

Eclipse or porcelain with book-matching?

Eclipse is an authentic natural material with individual batch variation and uncontrollable geological authenticity – every slab is unique. Porcelain with book-matching (e.g. Optimum Surfaces Zenith Storm, Laminam Calacatta) offers an identical dramatic look with reproducibly consistent batch variation, the same technical advantages (acid-proof, heat-proof, UV-stable, suitable for outdoors) and usually a more favourable price. The choice is one between geological authenticity (Eclipse natural stone) and controllable reproducibility (porcelain).
