Marquina Black Marble
Quarried from the Markina region of the Basque Country in northern Spain, Marquina Black Marble has been used in architecture and interior design for centuries. It is a bituminous limestone, and its deep black color comes from naturally occurring bitumen trapped within the stone during formation. The result is a dense, fine-grained surface crossed by white veining, a contrast that has made it one of the most recognized black marbles in the world.
Calcite is the main mineral present in Marquina Black Marble, making up approximately 98% of the stone's composition. That calcite content is responsible for both the characteristic white veining and the stone's position on the Mohs hardness scale at approximately 3. Understanding this helps homeowners and designers make informed decisions about placement and maintenance.
Where Marquina Black Marble Works Well
Marquina Black Marble is suited to both classic and contemporary interiors. In residential settings, it appears most often in bathroom walls and vanities, kitchen countertops and islands, fireplace surrounds, and feature walls. It is also used for stair risers, reception desk cladding, and elevator surrounds in commercial settings. Trade professionals working on larger projects can apply for a trade account to access dedicated support.
For bathroom applications, the stone works well as wall cladding and shower surrounds where it is not exposed to acidic cleaners or prolonged standing water without proper sealing. In kitchens, the stone can perform well if sealed and maintained consistently, though acidic spills will etch the surface. Trays and coasters help protect the finish.
Finishes and Fabrication
Resin fill is standard practice for Marquina Black Marble and is not considered a flaw in the material. Because the stone is relatively delicate in structure, mesh and resin backing is commonly applied before fabrication and installation to stabilize the slab and minimize surface irregularities. This is part of how the material is prepared for use rather than an indication of lower quality.
When planning a large installation, reviewing slabs in person allows for better control over vein matching and tonal consistency. Slabs are available to view across four showroom locations in Reno, Sacramento, Minden, and Fernley. Free design consultations are available at each location to help guide material and layout decisions.

Care and Maintenance
Because Marquina Black Marble is a calcite stone, it reacts to acids. Cleaning products with acidic formulations, citrus-based sprays, and vinegar will etch the polished surface over time. pH-neutral stone cleaners are the correct choice for routine maintenance.
Sealing is an essential part of caring for this marble. A penetrating sealer should be applied every 6 to 12 months depending on use and exposure. Regular sealing keeps the stone resistant to moisture and aids in stain prevention. Wiping up spills promptly before liquids have time to penetrate the surface is equally important.
For polished floors, door mats, regular dust control, and soft pads under furniture help protect the finish. In areas with heavier foot traffic, a honed finish is worth considering, as it tends to show wear less visibly than a polished surface.
View Slabs in Person
Marquina Black Marble slabs are available to view at four showroom locations in Reno, Sacramento, Minden, and Fernley. Seeing the stone in person allows for a more accurate read of veining, tone, and finish before committing to a layout. Free design consultations are available at each location to help guide material and placement decisions. Visitors can also find local showroom details before making the trip.

Frequently asked questions
Marquina Black Marble is quarried in the Markina region of the Basque Country in northern Spain, situated between the cities of Bilbao and San Sebastián. The stone takes its name directly from this region and has been extracted from these quarries for centuries.
Marquina Black Marble sits at approximately 3 on the Mohs hardness scale. It can be scratched by harder materials and is sensitive to acidic substances, which can etch the surface. It performs best where it is not subject to heavy abrasion. Bathroom walls, vanities, feature walls, countertops with appropriate care, and moderate-traffic flooring are all suitable placements.
Yes. Because it is a calcite-based stone with some porosity, Marquina Black Marble should be sealed with a penetrating stone sealer every 6 to 12 months, though frequency may vary based on usage and exposure. Sealing helps prevent staining and reduces the surface's vulnerability to moisture. Even sealed stone benefits from prompt cleanup of spills.
Marquina Black Marble slabs are typically available in polished, honed, and brushed finishes. A polished finish produces the highest contrast between the black field and white veining, with a reflective surface that emphasizes the stone's depth. A honed finish delivers a matte, smooth surface with less glare and is often preferred in wet areas or higher-traffic floors. A brushed finish adds subtle texture to the surface.
It can, with some considerations. The stone is sensitive to acidic substances, including citrus juice, vinegar, wine, and acidic cleaning products, all of which can etch the polished surface. In a kitchen setting this means using cutting boards, placing coasters under glasses, wiping spills immediately, and cleaning with pH-neutral products. With consistent sealing and proper daily care, Marquina Black Marble can work well as a countertop or island surface.
