Bianco Carrara MarbleGreek Key Corner, Polished
A polished Carrara and blue-gray marble corner piece that carries a Greek key border neatly through a right angle.
This 4 × 4 corner finishes a Greek key border where two runs meet. Small squares of white Carrara and soft blue-gray marble build the pattern, with gray veining showing through the white.
The polished face reflects light and deepens the contrast between the pale and blue-gray squares. Use it to frame a wall, backsplash or bath surround. It is sold per item. Your sample comes from the lot we have in stock now, so it shows that lot's actual color range and finish. Future lots may look lighter, darker, or more veined, so order your full quantity plus 10% at once to keep the whole job from one lot.

Care & Cleaning
Seal It
Apply a penetrating stone sealer after installation and follow the sealer maker's directions. Reseal as needed to help guard the polished surface against stains.
Clean It
Use a pH-neutral stone cleaner and a soft cloth or mop. Avoid vinegar, acidic cleaners and abrasive pads, which can dull polished marble.
Expect This
Natural marble varies in color and veining from piece to piece. Polished marble can show etching and light wear over time.
Tile & Mosaic Depot supplies material only. Installation method, setting materials, and substrate are your installer's responsibility. Inspect every piece before setting; installation is acceptance, and installed material cannot be returned or claimed.
Questions
What size is this corner and how is it sold?
You get a 4" × 4" Greek key corner piece, sold per item. Order the number of corners your border layout needs.
Will my order look like the sample or photos?
Your sample comes from the lot we have in stock now, so it shows that lot's actual color range and finish. Future lots may look lighter, darker, or more veined, so order your full quantity plus 10% at once to keep the whole job from one lot.
How do I order a sample?
You can order up to 10 samples per order at $7.99 each. Samples ship free and go out within 1-3 business days.
Does this marble need to be sealed?
You can protect the polished surface with a penetrating stone sealer, and sealing is recommended for this marble. Follow the sealer maker's directions for application and reapplication.
Does this piece qualify for free shipping?
Free shipping over $1,999 applies to mosaics and moldings, and this piece is listed as a molding.
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.
