A black marble sink in Nero Marquina — deep black stone with crisp white lightning veins — is the fastest way to give a bathroom modern drama. We carve each one from a single Spanish-black-class Anatolian block, to your dimensions, and deliver worldwide with insured DDP shipping.
Nero Marquina pairs spectacularly with brass and matte-black fixtures; in a light bathroom it reads as sculpture, in a dark one as pure sophistication. Fluted fronts catch the light along every carved ridge.
Formats include wall-mounted basins with backsplash, above-counter vessels and vanity tops. Like all marble, Nero Marquina is a calcite stone with a Mohs hardness of about 3, so acidic splashes — lemon, vinegar, some toothpastes — can etch the surface. Per Natural Stone Institute care guidance, a penetrating sealer resists staining but does not stop etching, so the practical routine is a pH-neutral (roughly pH 7) stone cleaner rather than acidic household sprays. Marble that meets ASTM C503/C503M, the Standard Specification for Marble Dimension Stone, absorbs no more than 0.20% of its weight in water and carries a minimum compressive strength of 7,500 psi (52 MPa) and a modulus of rupture of at least 1,000 psi (7 MPa) — dense, strong stone, but still calcite. Black stone also shows water spots more than light marble; a 10-second wipe after use keeps it flawless.

Frequently Asked Questions
Is a black marble sink hard to keep clean?
No — a quick wipe after use prevents water spots, a pH-neutral (about pH 7) stone cleaner keeps the surface safe, and a yearly re-seal resists staining. Total effort is minutes per month.
Do black marble sinks scratch or etch easily?
Nero Marquina is a calcite marble at roughly Mohs 3, so acidic liquids can etch it and it is softer than quartz or granite. Etching is surface chemistry, not staining, so a sealer won't stop it — avoid acidic cleaners and wipe spills promptly. Light etch marks can be honed out; that is why we finish and can refinish each basin by hand.
What is Nero Marquina marble?
Nero Marquina is a fine-grained black calcite marble with high-contrast white veining, prized for modern statement bathrooms. As a calcite marble it falls under ASTM C503/C503M, which sets a minimum density of 162 lb/ft³ (2,595 kg/m³) and a maximum water absorption of 0.20% by weight — so the stone is heavy and close to non-porous before any sealer is applied.
Do you make black marble sinks in custom sizes?
Yes — every Nero Marquina piece is carved to order, so any dimension is possible at typically the same price. Finished pieces are held to the cut-to-size bands in the Natural Stone Institute's Dimension Stone Design Manual (2022): ±1/16 in. (±1.5 mm) on face dimensions up to 6 ft and ±1/4 in. (±6 mm) on thickness over 2 in.
How much clearance should I leave when sizing the vanity?
Allow about 1/4 in. (6 mm) of slack per side. Solid stone over 2 in. thick carries a ±1/4 in. thickness tolerance and ±1/16 in. on face dimensions under the Natural Stone Institute's 2022 cut-to-size bands, so a reveal absorbs that variation while a zero-clearance opening does not. Our shop drawing guide covers what to check before approving dimensions.
