On hand at our Los Angeles yard: one slab of Portoro, a 2 cm black quartzite from Italy in a leather finish. Lot 231033 measures about 130″ × 75″.

This slab

The recorded size of a slab in this lot is 130″ × 75″, about 68 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 Italy.

The leather finish is lightly textured, with a softer look than a full polish. Two centimeters is a standard slab thickness for counters, vanities, and wall cladding.

In the yard

Lot 231033 at our Los Angeles yard shows one slab in stock, none on hold, and one slab available. Available means in stock minus slabs on hold.

With one slab available, it suits a project that can be cut from a single piece.

Where it works

For this kind of stone, the usual applications are kitchen countertops, islands, and vanities. The right use still depends on the finish, the thickness, and how the slab will be cared for after it is installed. Inspiration photos show this stone in a Fireplace.

The material

Quartzite begins as sandstone and is metamorphosed into a hard, quartz-rich stone. It is chosen for kitchens and islands when a project wants marble-like movement with more scratch and heat resistance than marble. Density and absorbency still vary by quarry, so sealing should be confirmed on the slab in front of you, not assumed from the name. Movement can change across one lot, which is why the pieces are best compared side by side in daylight.

About Portoro

Portoro Quartzite is a striking natural stone from Italy that redefines luxury with its intense, midnight-black canvas. It is characterized by a sophisticated network of intersecting white and golden veins that create a dynamic, high-contrast aesthetic. While its name and appearance pay homage to the famous Nero Portoro marble from the Gulf of La Spezia, this quartzite variety offers superior durability, boasting high resistance to scratches and heat. This makes it an ideal choice for high-traffic areas like kitchen countertops and statement feature walls. Its unique mineral composition allows for a mirror-like polish that beautifully reflects light, adding depth and opulence to any contemporary or classical design.
