The slabs
Size and figure, selection by selection
Six stones photographed in the same setting at the same scale: first the Italian ones, Ligurian slate from the Val Fontanabuona and Cardosia from Versilia, then the Brazilian slates from Minas Gerais. Brazilian slabs come in a standard size, 230 × 140 cm, and here differ only in colour; Ligurian slate, quarried underground, normally reaches 250 × 130 cm.
Ardesia Ligure
250 × 130 cm2 cm and 3 cm thick
Anthracite black with a natural cleft face and a light, wavy relief: it is the slate of the Val Fontanabuona (Genoa), quarried underground from inclined beds and worked in Liguria for centuries for roofs, stairs and billiard beds. Outdoors the black lightens to a silver-grey patina. Slabs are normally made up to 250 × 130 cm; larger sizes to order.

Cardosia
250 × 160 cm2 cm and 3 cm thick
Anthracite grey leaning to blue, crossed by sharp white veins that intersect diagonally. It is Pietra del Cardoso, quarried at Stazzema, in the upper Versilia (Lucca): geologically it is not a slate but a metamorphic sandstone, sold alongside slates for its colour and uses. More compact and less fissile, it is worked in thick slabs, also polished, for floors, stairs and worktops.

Ardesia Mare
230 × 140 cm2 cm and 3 cm thick
An even graphite grey with a fine, regular cleft surface. It is a Brazilian slate from the state of Minas Gerais, where almost all of Brazil's slate is quarried; «Mare» is the trade name under which it is sold in Italy. It keeps its colour over time and withstands frost and water: it is the most used for exteriors and pool surrounds.

Ardesia Verde
230 × 140 cm2 cm and 3 cm thick
Sage green leaning to blue-grey, with a few thin darker veins: the colour comes from chlorite and phengite. It is a Brazilian slate from Minas Gerais, with a natural cleft face, used for walls, bathrooms and floors where a quiet green is wanted.

Ardesia Viola
230 × 140 cm2 cm and 3 cm thick
A deep plum purple with brown reflections and a few light cleavage threads. It is a Brazilian slate from Minas Gerais, also known as Purple or Roxa: the rarest colour of the family, used for accent floors and cladding.

Ardesia Multicolor
230 × 140 cm2 cm and 3 cm thick
A rust and ochre ground with blue-grey patches: the warm tones come from iron oxides on the cleavage planes, and every slab is different. It is a Brazilian slate from Minas Gerais; Indian and Chinese rust slates with the same look are also sold, mainly as cladding strips.
Request this selection: Ardesia MulticolorAbout the stone
Slate is a metamorphic rock with a schistose structure that splits naturally into thin slabs along parallel planes. The cleft surface is irregular and highly slip-resistant, suited to exteriors, pool surrounds and roofs. In Italy slate means the Val Fontanabuona, in Liguria: black, quarried underground and worked for centuries for roofs, stairs and billiard tables. From Versilia comes Cardosia, the blue-grey, white-veined Pietra del Cardoso, sold alongside slates. The colours come from Brazil, from the state of Minas Gerais: Mare grey, green, purple and the rust-patched multicolor, in calibrated slabs of regular size.

How it behaves once laid
Stone changes with the surface it covers: on a continuous wall the figure reads in full, on a floor you walk across it. These are reference settings.
Reference renderings, not Eurostone supplies: they show the material in place, not a completed project.
