This is the critical companion to the Cosmic White ledger panel. The Cosmic White Stacked Stone Corner Piece is an "L-shaped" unit designed to wrap around 90-degree external corners, providing a seamless transition that hides the raw, unfinished ends of the stone.

PRODUCT TITLE

Cosmic White 6" x 18" Natural Quartzite Stacked Stone Corner Piece

PRODUCT DESCRIPTION

Ensure a professional, high-end finish for your masonry project with the Cosmic White Corner Piece. Specifically engineered to coordinate with the Cosmic White ledger panels, these corner units wrap around external edges to give your wall the appearance of solid, hand-cut stone blocks.

Crafted from premium natural quartzite, Cosmic White features a crystalline, "snow-white" aesthetic with subtle silver and cream highlights that shimmer slightly in the light. The split-face texture offers a rugged, multi-dimensional surface that creates dramatic shadows. Whether you are finishing a fireplace, a kitchen island, or an exterior home facade, these "L-shaped" corners eliminate visible seams and provide a cohesive, continuous look.

KEY FEATURES

• Seamless L-Shaped Design: Wraps around 90-degree corners to provide a finished architectural look.

FREQUENTLY ASKED QUESTIONS

How do I calculate how many I need? Corner pieces are sold by the vertical linear foot. Since each piece is 6 inches high (0.5 feet), you will need two corner pieces for every one vertical foot of your corner. For a standard 8-foot tall wall corner, you would need 16 pieces.

Do these match the flat panels? Yes. These are manufactured from the same stone lots as the Cosmic White 6x24 flat panels. However, because it is natural stone, we recommend buying all your flat panels and corners at the same time to ensure the best color match.

Do I need to grout these? No. Like the flat panels, these corners are designed for a "dry-stacked" look. They fit tightly together, and no grout is required in the joints.

INSTALLATION & CARE TIPS

• Alternating Layout: To achieve the most natural look, alternate the direction of the "L" as you move up the wall. Most corner pieces have one long leg and one short leg; flipping them row-by-row prevents a vertical "seam" line from forming.

• White Thinset Only: This is vital for white quartzite. Gray thinset will bleed into the stone and make your "Cosmic White" look like a muddy grey.

• Adhesive: Use a high-tack, Large Format Tile (LFT) mortar to support the weight of the stone on vertical surfaces.

• Sealing: Apply a high-quality penetrating sealer after installation. This protects the white stone from UV yellowing outdoors and soot/staining near fireplaces.
