On hand at our Los Angeles yard: 18 slabs of Ardosia Nera Black Slate, a 2 cm black slate from Brazil in a honed finish. Lot SK134 measures about 89″ × 53″.
This slab
The recorded size of a slab in this lot is 89″ × 53″, about 33 square feet. Thickness is 2 cm. The color on record is black. Natural stone still varies inside that description, so the slab itself is the reference for movement and shade. This material is recorded as quarried in Brazil.
The honed finish is smooth and matte, without a high gloss. Two centimeters is a standard slab thickness for counters, vanities, and wall cladding.
In the yard
Lot SK134 at our Los Angeles yard shows 18 slabs in stock, none on hold, and 18 slabs available. Available means in stock minus slabs on hold.

Where it works
For this kind of stone, the usual applications are floors, wall cladding, and hearths. The right use still depends on the finish, the thickness, and how the slab will be cared for after it is installed.
The material
Slate is a fine-grained metamorphic stone that splits into layers. It is used for floors, cladding, hearths, and some counters. The surface is naturally textured, and color can run through gray, black, green, and rust. It is tougher underfoot than polished marble and does not need a gloss to look finished.
