Quartzite Slabs
Near-black quartzite with lightning-white veins. Also sold as Diamond Black; Negresco is the name stone people search.
Seal natural stone as recommended for the material and finish. Clean with pH-neutral products and address spills promptly to protect the surface.
Each lot is unique — review your selected slab before fabrication. Allow for natural variation, vein direction, and seam placement with your fabricator.
Availability follows the selected lot. Lead times depend on sourcing and project requirements. Contact us to confirm timing for your order.
Typically 2–3 weeks.
This is a graphic dark stone that works when the design needs weight on the island or perimeter. White or grey veins break up the field enough to avoid a flat black slab. It performs like quartzite in daily use: dense, practical, and less fussy than marble in a busy kitchen. Slab photos rarely capture the full contrast, so review in person if you can. Works with brass, nickel, and matte black hardware without fighting the stone for attention.
