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.

Product & Installation Guidance

Natural stone is a product of the earth — every piece is one of a kind. A little planning ensures your finished installation looks its best and lasts for decades.

Natural Variation
Color, veining, texture, shade, movement, finish, and sizing vary from piece to piece. Product photos and samples are a general reference and may not match the exact material you receive. These variations are inherent characteristics of natural stone — they are part of its beauty, not defects.

Before You Install

Order roughly 10% extra to allow for cuts, waste, and future repairs.
Blend tiles from multiple boxes as you work to achieve the most natural, balanced appearance.
Dry-lay and inspect the full layout before setting a single tile.
Installation constitutes full acceptance of the product, so review everything carefully first.

Sealing & Care
Natural stone should be sealed with a quality penetrating sealer before and after installation, and re-sealed periodically in wet or high-traffic areas. Clean only with a pH-neutral stone cleaner; avoid acidic products, bleach, vinegar, and ammonia, which can permanently etch the surface. Outdoor installations may weather or change tone over time with exposure.

Responsibility
Tile & Mosaic Depot is not responsible for improper installation, labor costs, substrate conditions, product misuse, or damage from improper handling, sealing, maintenance, or harsh chemicals. No claims, returns, or replacements can be accepted on installed material.

California Proposition 65: Some natural stone products contain substances known to the State of California to cause cancer or reproductive harm. For more information, visit www.P65Warnings.ca.gov.

Order a Sample First

Seeing real stone in your own space — under your own light, beside your own finishes — is the best way to buy with confidence. We make it easy and affordable.

How It Works

What a Sample Shows
Samples help you evaluate the general color, texture, finish, and overall character of a product before committing to a full order. Because natural stone varies from piece to piece, your sample is representative — it may not capture the complete range of variation across an entire lot. For current lot photos, just ask our team.

Good to Know

Ordering a sample before a full purchase is always recommended, especially for natural stone.
