About Pietra Gray Marble 1×1 Polished Mosaic

Material Education

Pietra Gray is a sophisticated dark limestone-marble hybrid quarried in the mountain regions of the Middle East, prized for its deep charcoal and slate-gray tones punctuated by delicate white fossil veining. Its dense, fine-grained surface takes on a brilliant polish, revealing subtle silver and graphite undertones that shift beautifully under light. The stone's fossil-rich matrix gives each tile a quiet geological narrative, making it a favorite among designers seeking drama without excess.

As a natural stone, Pietra Gray will exhibit gentle variation in tone and veining from piece to piece — this organic character is the hallmark of authentic stone and contributes to a truly one-of-a-kind installation.

About this mosaic: These 1×1 inch square chips are pre-mounted on a mesh-backed sheet, streamlining installation and ensuring consistent spacing across your surface. The sheet format allows large areas to be tiled quickly while maintaining the precise, jewel-like grid of small squares.

Design & Inspiration

Pietra Gray's deep charcoal palette pairs beautifully with brushed brass or matte black fixtures, warm white oak cabinetry, and crisp white marble accents, making it equally at home in moody contemporary interiors and refined transitional spaces. Its cool gray tones also complement polished chrome hardware and concrete-look surfaces for a clean, urban aesthetic.

The 1×1 format creates a densely textured, almost woven visual effect that adds depth and tactile interest to backsplashes and feature walls without overwhelming the space. On a shower floor, the small chip size provides excellent grip via grout lines while delivering an upscale spa-like finish.

Popular design combinations: Pietra Gray 1×1 mosaic floors paired with large-format Calacatta Gold marble wall tiles and brushed brass rainfall shower fixtures for a luxurious, high-contrast master bath.

Pietra Gray is a striking dark stone of limestone-marble composition, sourced from quarries in the Middle East, celebrated for its deep charcoal base threaded with fine white fossil veining. Its dense, compact grain and rich tonal depth make it one of the most versatile dark stones available for luxury residential and commercial applications.

Each 1×1 inch chip is polished to a high sheen, intensifying the stone's graphite and silver undertones and giving the mosaic a luminous, reflective quality. Pre-mounted on mesh backing, these sheets align quickly and accurately, dramatically reducing installation time compared to hand-setting individual pieces.

This mosaic is ideal for bathroom shower floors, kitchen backsplashes, and powder room feature walls where a refined, dramatic look is desired. As a clearance or special-order item, ordering a sample is strongly recommended to confirm color and variation match your project before purchasing full quantities.

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: Pietra Gray is a porous natural stone that must be sealed prior to installation and resealed every 12 months in wet areas such as showers. Apply a penetrating impregnating sealer formulated for dark stones to prevent water infiltration and grout haze absorption. Test sealers in an inconspicuous area first, as some topical sealers can slightly alter the stone's color.

Cleaning: Clean with a pH-neutral stone cleaner diluted in warm water and a soft cloth or non-abrasive sponge. Avoid acidic cleaners, vinegar, citrus-based products, or bleach, which can etch the polished surface and dull the stone's natural sheen. Wipe up spills promptly, especially acidic liquids such as coffee, wine, or juice, as the polished finish is susceptible to etching.

Installation: Use white or light-gray thinset mortar to prevent bleed-through on lighter veining; a dark-pigmented thinset is also acceptable given the stone's deep charcoal base. Apply non-sanded grout for the tight 1×1 mosaic joints to ensure clean, crack-free lines. Back-butter each sheet with a thin layer of thinset for full coverage, and ensure mesh sheets are properly aligned at seams for a seamless finished appearance.

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.

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.
