Nero Marquina Marble Crown Molding

Nero Marquina Marble Crown Molding is a black marble trim piece sold individually by the piece. Because every piece is cut from natural blocks, veining and tone shift from tile to tile, giving each installation a pattern of its own. It finishes edges, transitions, and baseboards so the field tile ends with a clean line.

Black is decisive underfoot and dramatic on walls, sharpening whites and metallics around it. Keep surrounding surfaces light to let the dark field carry the room.

Marble is metamorphosed limestone, formed when heat and pressure recrystallize calcite into the veined, light-reflective stone quarried for centuries of architecture. Every tile is cut from natural blocks, so veining and tone vary from piece to piece, which is the material's signature rather than a defect. Marble stays cooler than the surrounding air, takes a high polish, and brings a depth of color that printed surfaces approximate but do not match.

Marble is a calcite stone and needs sealing at installation and roughly once a year after, depending on traffic. Wipe spills quickly, especially wine, citrus, and vinegar, which etch the surface on contact. Clean only with stone-safe pH-neutral cleaners; never use vinegar, bleach, or abrasive powders. Use walk-off mats at entries and felt pads under furniture. Install with white thinset to avoid bleed-through, and dry-lay tiles first to blend natural variation across the floor or wall.
