Key Features

• Large 48″ × 48″ format substantially reduces grout lines, enhancing seamless visual flow and allowing the marquina veining to span broadly without interruption. 
• Dual finishes let you choose between a glossy reflective surface (polished) or a subtler, less reflective surface (matte), depending on lighting & design goals. 
• Rich black tones with crisp white veining deliver striking contrast — excellent for dramatic looks in monochrome or accent-bold color palettes.
• Porcelain construction provides durability, easier maintenance, and resistance to water and stains compared to natural marble.

Care & Maintenance

• Clean regularly with a soft cloth or mop using a mild, pH-neutral cleaner; avoid acidic or abrasive cleaners that can damage polished surfaces or dull matte surfaces. 
• Wipe up spills quickly, especially liquids that could stain (wine, coffee, etc.), especially on polished finishes.
• Use light or matching color grout & thin-set to avoid color contrast at joints.
• For installation, ensure the substrate is flat and properly prepared; large tiles require precise installation to avoid lippage.
• Sweep or vacuum often to remove grit that could scratch the finish.
