Jandira Especial is a Brazilian migmatite from the Precambrian shield region with a powerfully speckled black-and-white groundmass and warm rust-pink feldspar accents. A classic “salt and pepper” migmatite with high compressive strength, acid resistance and full suitability for frost — a strongly characterful choice for kitchen worktops, stairs and external façades.
Brasilianischer Migmatit (hochgradig metamorphes Mischgestein, im internationalen Handel oft als „Granit" geführt) aus den präkambrischen Schildgebieten Brasiliens. Mineralisch dominiert von hellem Feldspat-Quarz-Leukosom mit dunkelmafischer Phenokristalle (Melanosom: Pyroxene, Hornblenden, Biotit) und warm-rosa Kalium-Feldspat-Akzenten mit Eisenoxid-Pigmentierung. Mohshärte ca. 6, hohe Druckfestigkeit, niedrige Wasseraufnahme, vollständig säure- und hitzebeständig.
Jandira Especial is a Brazilian migmatite from the Precambrian shield regions of Brazil — probably from the states of Bahia, Espírito Santo or Minas Gerais, the same major geological structure that also yields materials such as Cosmic Black, Magma Gold and Night Dream. Geologically it is a migmatite (a high-grade metamorphic mixed rock) in which the parent rock was partially melted under extreme pressure and temperature loading.
In the international stone trade, Jandira Especial is frequently carried simply as a “granite” — commercially widespread, but petrographically more precisely a migmatite. This classification explains the characteristic slab: two clearly distinguishable components — the pale, crystallised melt fraction (leucosome: a feldspar-quartz composition) and the dark, residual mafic fraction (melanosome: pyroxenes, hornblendes, biotite).
In the slab, Jandira Especial shows a classic “salt and pepper” character: a pale, finely speckled ground image with evenly distributed dark mineral dots, accentuated by warm pink to rust-red-brown feldspar phenocrysts. The warm pink accents are potassium-feldspar-rich areas with iron pigmentation — a characteristic peculiarity of many Brazilian migmatites, which lends the otherwise coolly black-and-white ground composition a warm tonality. In places the finest foliation lines are discernible, reproducing the original metamorphic direction of pressure.
For the application that means: Jandira Especial is a first choice for robust kitchen worktops with a strongly characterful accent, stairs under high loading, façade elements with external exposure, floor areas and prestige areas. Brazilian migmatites of this class typically show high compressive strength, low water absorption and full acid resistance. Steel knives leave no scratches, wine and lemon no etch marks, hot pans can be set down directly.
At ROSSITTIS we currently carry Jandira Especial as 24 raw slabs in 20 mm thickness with a polished finish. On request we produce kitchen worktops, islands, vanity tops, wall claddings, floor and wall tiles, stairs, window sills, skirtings, façade elements and project-specific custom cuts from it.
If you want to compare Jandira Especial with other materials: stylistically close are other Brazilian speckled migmatites with warm accents — Verniciato, Rosa Beta (classically Sardinian, but a similar pictorial idea), Juparana granites, Capão Bonito. Among the calmer solid-colour granites, Bianco Sardo, Bianco Romano and Beola Bianca are similar in character. Anyone looking for the same “salt and pepper” image in robust, acid-resistant form and with a warm accent will find a very good choice in Jandira Especial.
Our honest assessment: Jandira Especial is a distinctly versatile choice for projects that call for a robust natural stone with strongly characterful, lively mineral markings. Anyone looking for a calm monochrome solid-colour look is better served by other materials. But anyone who values the classic Brazilian migmatite character with warm feldspar accents — while needing the full robustness of a high-performance hard stone — gets a very coherent stone in Jandira Especial.

Finishes
Jandira Especial 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.
Care & fabrication
Jandira Especial is a dense Brazilian migmatite with high compressive strength, low water absorption and very good acid, heat and frost resistance.
Daily cleaning: a soft microfibre cloth, warm water and a pH-neutral natural stone cleaner.
Do not use: concentrated acids, steel wool, coarse scouring sponges.
Sealing: on polished surfaces, recommended every 18–36 months depending on the loading.
Kitchen worktop: hot pans can be set down directly. Steel knives leave no scratches. Wine and lemon leave no etch marks. Nevertheless do cutting work on a separate chopping board, to spare the blades.
Outdoors: suitable for frost given correct installation with a fall and drainage. Use de-icing salt sparingly in winter.
Repair: scratches in the polish can be evened out by professional re-polishing.
Frequently asked questions
Is Jandira Especial really a granite?
Petrographically it is more precisely a migmatite (a high-grade metamorphic mixed rock) — the pale areas are crystallised melt (leucosome), the dark dots are the mafic-residual fraction (melanosome). In international trade it is often carried simply as a “granite”. What is relevant for the application is the full hard stone robustness of both classifications.
Where does Jandira Especial come from?
From the Brazilian migmatite complexes, probably from Bahia, Espírito Santo or Minas Gerais — part of the Precambrian Brazilian craton.
Is Jandira Especial suitable for a kitchen?
Yes, excellently. With high compressive strength and full acid and heat resistance, Jandira Especial is a very robust choice for kitchen worktops.
Is Jandira Especial suitable for external applications?
Yes, fully. Brazilian migmatites have very low water absorption and are suitable for frost. Given correct installation, they are approved for all external applications.
