About Rockart Medallion Black & White Marble-Look Porcelain Mosaic

Material Education

This mosaic features high-definition porcelain crafted to replicate the timeless contrast of black and white marble, capturing the crisp veining and tonal depth of classic natural stone without the variability of quarried material. The porcelain body is fired at high temperatures, producing a dense, non-porous tile with a refined surface that mimics polished marble's luminous sheen. Deep charcoal and jet-black tones are balanced by bright white grounds, creating a graphic, high-contrast palette.

While porcelain provides greater consistency than natural stone, subtle tonal shifts between pieces are intentional and add visual depth — a hallmark of quality marble-look printing technology.

About this mosaic: This 12×12 inch mesh-backed medallion mosaic features an intricate circular medallion pattern composed of precisely cut black and white porcelain chips arranged in a decorative rosette design. The mesh backing keeps the medallion perfectly aligned and dramatically speeds up installation, allowing a single sheet to be set as a focal point with minimal layout effort.

Design & Inspiration

The bold black-and-white palette pairs beautifully with matte black fixtures, polished chrome hardware, white oak cabinetry, and warm brass accents, bridging the gap between classical elegance and modern graphic sensibility. This tile suits a wide range of styles — from Victorian and Art Deco interiors to sleek contemporary and transitional spaces.

The medallion format is purpose-built as a statement centerpiece: ideal for entryway floors, shower pan focal points, or powder room feature walls where a single sheet becomes the room's defining element. Its 12×12 footprint makes it easy to center in a doorway or vanity alcove for maximum visual impact.

Popular design combinations: pair this medallion as a shower floor centerpiece surrounded by large-format white matte porcelain field tiles and matte black linear drains for a spa-like Art Deco aesthetic.

The Rockart Medallion Black White Marble Porcelain Mosaic brings the grandeur of classical marble inlay to modern interiors through precision-printed porcelain technology. Rendered in striking black and white, the intricate medallion design replicates the look of hand-cut stone marquetry found in historic European architecture.

Set on a convenient 12×12 mesh-backed sheet, the medallion pattern arrives pre-assembled and ready to install — simply position, press, and grout. The polished-look porcelain surface reflects light beautifully, amplifying the contrast between dark and light chips and creating a jewel-like focal point on any floor or wall.

This mosaic is ideally suited for entryway floors, powder room floors, shower floors, and feature walls where a single decorative accent tile is desired. As a clearance or specialty item, ordering a sample is strongly recommended to confirm color and scale in your space before purchasing your full quantity.

Free Shipping: As a mosaic, 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: Porcelain is non-porous and does not require sealing. However, if sanded grout joints are used, sealing the grout lines is recommended annually in wet areas such as showers to prevent staining and mildew.

Cleaning: Clean with a pH-neutral stone and tile cleaner or mild dish soap diluted in warm water. Avoid acidic cleaners (vinegar, citrus-based), bleach, or abrasive scrubbers, which can dull the polished surface finish and damage grout joints over time.

Installation: Use white polymer-modified thinset mortar to prevent any dark adhesive from telegraphing through lighter chips. Install the mesh-backed sheet face-up, pressing firmly and evenly across the entire surface. Use non-sanded grout for joints under 1/8 inch. Center the medallion carefully before setting — dry-lay surrounding field tiles first to confirm alignment and avoid awkward cuts at perimeter edges.

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.
