The Micronesia Nauru Royal White mosaic brings together two of nature's most luminous materials — pure white Thassos marble from the Greek islands and natural shell — in an intricate, jewel-like geometric pattern that commands attention in any space.

Each mesh-backed sheet is finished with a polished surface that amplifies the brilliant white of the Thassos chips and the iridescent shimmer of the shell inlays, creating a mosaic that plays beautifully with both natural and artificial light. The mesh backing simplifies installation considerably, keeping all chips and shell pieces in precise alignment without the need for individual placement.

This mosaic is ideally suited for interior feature walls, luxury shower surrounds, spa backsplashes, and decorative niches; as a clearance or specialty item, we recommend ordering a sample first to confirm color and pattern scale in your specific lighting conditions.

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: Both Thassos marble and natural shell require sealing before grouting and regularly thereafter. In wet areas such as showers, apply a penetrating stone sealer every 6–12 months to protect against water intrusion and staining. Because Thassos is an exceptionally bright white stone, consistent sealing is critical to prevent discoloration over time.

Cleaning: Use only pH-neutral stone cleaners — never acidic products such as vinegar, citrus-based cleaners, or grout haze removers, as these will etch the polished marble surface and can permanently damage the natural shell pieces. Wipe up spills promptly, especially oils and colored liquids, as the polished finish is more susceptible to etching and spotting than a honed surface.

Installation: Install using white polymer-modified thinset mortar to prevent any gray show-through on this bright white stone. Use non-sanded grout for the fine mosaic joints to avoid scratching the polished marble and shell surfaces. Align mesh-backed sheets carefully on the wall before pressing firmly, and check that shell inlays are fully supported by thinset with back-buttering as needed for complete coverage.

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
Samples are just $7.99 each with free shipping, and they ship in 1–3 business days. Sizes vary by material and availability, typically ranging from 3"×3" up to 8"×8". Exact dimensions aren't guaranteed, but every sample is cut from the same material you'll receive in a full order.

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

  • Samples are final sale — non-returnable and non-refundable.
  • Ordering a sample before a full purchase is always recommended, especially for natural stone.
  • Planning a larger or custom quantity? Contact us for a tailored quote.
