About Nero Marquina Marble Polished Crown Molding

Material Education

Nero Marquina is a striking black marble quarried in the Basque region of Europe, prized for its deep, uniform jet-black ground and bold white calcite veining that cuts through the stone in dramatic, high-contrast streaks. Its polished surface amplifies the stone's natural luster, producing a mirror-like sheen that makes the white veins appear almost luminous against the dark matrix. The result is one of the most visually commanding natural stones available in the premium tile market.

As a genuine natural stone, each piece of Nero Marquina will display subtle differences in vein placement, thickness, and patterning — characteristics that authenticate its origin and give every installation a one-of-a-kind quality.

About this molding: This crown molding is a linear architectural trim piece cut and profiled from solid Nero Marquina marble, designed to create elegant transitions at wall-to-ceiling junctions, cabinetry tops, or as a decorative border accent. Sold per linear foot, it installs with standard marble adhesive and brings a finished, bespoke look to any stone application.

Design & Inspiration

Nero Marquina's black-and-white palette pairs beautifully with polished chrome, brushed gold, and matte brass fixtures, as well as white Carrara or Thassos accents, warm white oak cabinetry, and deep charcoal grout — suiting bold contemporary, Art Deco, and refined transitional interiors. Its high-gloss polished finish adds a sense of luxury and formality that elevates both minimalist and maximalist design schemes.

As a crown molding, this profile is ideal for capping tiled bathroom walls, framing kitchen backsplash fields, or defining a fireplace surround — the curved profile catches light and adds sculptural dimension that flat field tile cannot achieve. The dramatic contrast of white veining on a black ground makes it an effective design focal point even in small quantities.

Popular design combinations: pair this Nero Marquina crown molding with a field of polished white Thassos or Carrara marble tile for a classic black-and-white bathroom scheme accented by brushed gold fixtures.

Premium Natural Stone

Secure Packaging

Nero Marquina marble is one of the world's most celebrated black stones, characterized by its deep jet-black body and vivid white calcite veining — quarried in Europe and prized across centuries of architectural and interior design applications. This crown molding is precision-cut and profiled from solid Nero Marquina slabs, delivering the same premium stone quality found in luxury hotels and high-end residences.

The polished finish brings out the full depth of the black marble and the brilliance of its white veins, creating a sleek, reflective surface with strong visual impact. The classic crown profile adds a three-dimensional architectural detail that transitions spaces gracefully and lends a bespoke, finished look to any tiled wall, niche, or surround.

This molding is an ideal finishing trim for bathroom walls, shower niches, fireplace surrounds, kitchen backsplashes, and cabinetry transitions — anywhere a polished stone edge detail is desired. Because this is a clearance or specialty item, we recommend ordering a sample to verify color match and vein character before committing to a full order.

Free Shipping: As a molding, this product qualifies for free curbside shipping on orders over $1,999 within the continental U.S. Orders below that threshold ship at standard rates calculated at checkout.

Processing & Delivery: Orders are processed within 2–3 business days. Large orders ship via LTL freight — curbside delivery only. An adult must be present to sign for delivery. Estimated transit: 2–10 business days after shipment.

30-Day Returns: Uninstalled tile may be returned within 30 days of delivery. Inspect all tile carefully before installation — installed tile cannot be returned or exchanged. Samples are final sale.

Exclusions: Free shipping does not apply to Hawaii, Alaska, U.S. territories, or international addresses. Additional charges may apply for remote delivery areas.

Sealing: Seal this Nero Marquina crown molding with a high-quality penetrating stone sealer before installation and re-seal every 12 months in bathroom or kitchen environments. Although dark marble shows water spots and etching less readily than white marble, the polished finish benefits from regular sealing to prevent mineral deposits from dulling its mirror-like sheen.

Cleaning: Clean with a pH-neutral stone cleaner and a soft, damp cloth — never use acidic cleaners, vinegar, citrus-based products, or abrasive pads, as these will etch and dull the polished surface permanently. Wipe spills promptly, especially acidic substances like soap scum, coffee, or hard water, which can leave visible marks on the high-gloss finish.

Installation: Use a white or gray polymer-modified thinset adhesive appropriate for marble; gray thinset is acceptable for Nero Marquina given its dark color. Ensure the substrate is flat and plumb before adhering, and use painter's tape to hold the molding in position while the adhesive cures. Apply a matching dark unsanded caulk (rather than grout) at joints and corners to allow for minor movement and preserve the polished profile edge.

Important: Inspect all tile before installation. Variations in color, veining, and texture between pieces are natural characteristics of genuine stone — not defects. Order 10% overage for cuts, waste, and future repairs. Tile & Mosaic Depot specialists are available M–F 8:30AM–5PM PST at 855-797-8453.

Why Order a Sample
A screen can't show you how Calacatta veining reads under your kitchen lights or how a porcelain finish sits next to your cabinet color. A sample can. It's the single best way to buy stone or porcelain tile with confidence — and the cheapest mistake you'll ever avoid.

How It Works
Samples are $7.99 each. Samples ship free and leave our warehouse within 1–3 business days. Sizes vary by material and availability — typically 3"×3" up to 8"×8" — and every sample is cut from the same material stocked for full orders.

What a Sample Shows
Color, texture, finish, and overall character. Because natural stone varies piece to piece, one sample represents the material but can't show the full range of a lot. Porcelain samples are highly representative of the production run. Want to see the current lot before you commit? Ask us — we'll send photos.

Good to Know

Samples are final sale — non-returnable and non-refundable.
We recommend sampling before every full order, especially for natural stone.

Talk to a Specialist
Our stone and tile specialists will help you narrow it down. Call (855) 797-8453 or email sales@tileandmosaicdepot.com, Monday–Friday, 8:30 AM–5 PM PT.

How Your Order Ships
In-stock orders leave our warehouse within 2–3 business days. Stone, porcelain, and mosaic ship on a pallet via scheduled LTL freight and arrive 2–10 business days after dispatch, depending on destination. You'll get tracking and the carrier's name by email the day it ships.

Freight Delivery — What to Expect

The carrier calls you first. Every freight delivery is by appointment. Expect a call or text to set a window before the truck is dispatched.
Curbside delivery. The driver unloads to the curb or driveway. Freight does not include carrying material indoors or into a garage — plan for a helper or a hand truck.
Someone 18+ must sign. Inspect the pallet before signing. Note any damage, shortage, or broken shrink-wrap on the delivery receipt — this is what makes a claim valid.
Truck access. The address must be accessible to a full-size freight truck with enough space to unload.

Free Shipping
Free curbside freight on qualifying mosaic and molding orders over $1,999 in the continental U.S. Field tile, porcelain, and other product types ship at freight rates shown at checkout. Not available to Hawaii, Alaska, U.S. territories, or international addresses.

Damage & Shortages
Report within 3 calendar days of delivery with photos of the pallet, packaging, and affected pieces to sales@tileandmosaicdepot.com. Verified claims are covered. Shortages of 1–5 pieces are refunded rather than reshipped — which is why we recommend ordering 10% overage.

30-Day Returns
Uninstalled tile in full, unopened boxes may be returned within 30 days of delivery. Return freight is paid by the customer. Partial boxes, opened boxes, installed material, and samples are final sale.

Questions Before You Order?
Call (855) 797-8453 or email sales@tileandmosaicdepot.com, Monday–Friday 8:30 AM–5 PM PT. If you're unsure about freight access at your address, ask us before checkout — we'll flag anything that could hold up delivery.

Natural Variation
Quarried stone varies in color, veining, shade, movement, and finish from piece to piece and from lot to lot. Screen photos and samples show the range, not the exact tile you'll receive. Variation is the nature of the material and is never grounds for return. Porcelain is far more consistent, but shade and pattern can still shift between production runs — buy your full quantity in one order.

Before You Install

Order 10% overage. Covers cuts, breakage, and spares for future repairs. Reorders may not match in tone or lot.
Inspect every piece before setting. Pull from all boxes, blend, and dry-lay the full area. Installation is acceptance — no claims are honored once tile is set.
Hire a qualified installer. Natural stone and large-format porcelain require experience with the material. Your installer is responsible for substrate, setting materials, and method.

Sealing & Care
Natural stone should be sealed with a penetrating sealer and re-sealed periodically in wet and high-traffic areas. Clean with a pH-neutral stone cleaner only — vinegar, bleach, ammonia, and acidic cleaners etch marble, limestone, travertine, and onyx permanently. Porcelain does not require sealing. Outdoor stone weathers and shifts in tone over time; this is expected.

Responsibility
Tile & Mosaic Depot supplies material only. We are not responsible for installation, labor costs, substrate conditions, setting materials, product misuse, or damage from handling, sealing, maintenance, or chemicals. No claims, returns, or replacements are accepted on installed material.

California Proposition 65
Some natural stone and porcelain products contain substances known to the State of California to cause cancer or reproductive harm. Details at www.P65Warnings.ca.gov.
