Matrix 3D is a 2 cm black quartzite from Brazil, offered in a polished finish. Lot 16811 measures about 127″ × 76″, with 2 slabs available at our Los Angeles yard.

This slab

The recorded size of a slab in this lot is 127″ × 76″, about 67 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 polished finish is reflective and lets the color read clearly. Two centimeters is a standard slab thickness for counters, vanities, and wall cladding.

In the yard

Lot 16811 at our Los Angeles yard shows 2 slabs in stock, none on hold, and 2 slabs available. Available means in stock minus slabs on hold.

The slabs can be compared in daylight at our Los Angeles yard before anything is cut.

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 an Outdoor Bar / BBQ.

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 Matrix 3D

Matrix 3D is a mesmerizing quartzite from the rich mineral deposits of Brazil, specifically the Minas Gerais region. Often referred to as Matrix Granite due to its extreme durability, it is geologically a schist composed primarily of biotite and quartz. This stone is famous for its deep charcoal to obsidian background, which features a unique, scale-like texture that creates a dramatic three-dimensional effect. When processed with a high-pressure water finish, its silver-grey veins and metallic luster become even more pronounced. This "liquid metal" appearance makes it a premier choice for statement countertops and avant-garde architectural features.
