Cerdomus Alma Onice 24x48 Matte

Description

Cerdomus Alma Onice 24×48 Matte — Marble-Look Porcelain from Italy

The Cerdomus Alma Onice 24×48 Matte is a marble-look porcelain tile from Italy in a striking 24″x48″ large-format rectified format, with a matte (R10 A+B slip-rated) surface that performs equally well underfoot or on walls, indoors or out. Its warm honey-amber with translucent veining reminiscent of natural onyx captures the look of the prized banded onyx stones used in classical and Art Deco interiors with the durability and low-maintenance performance of modern porcelain — ideal for residential and light commercial installations across the Northeast US.

About the Alma Collection by Cerdomus

The Alma collection by Cerdomus is a curated journey through the world’s most prized marbles — sourced from exclusive quarries in Italy and the Middle and Far East, then reinterpreted in porcelain through high-definition digital ceramic technology. White, in all its unexpected shades, is the protagonist of the collection. Manufactured by Cerdomus in Castel Bolognese, Italy (a family-owned ceramics maker since 1969), Alma is offered in coordinated sizes and finishes so Onice can be installed alongside its sibling marbles for layered, designer interiors.

Design Notes — Why Specify Onice

The soft, glowing tonal range gives it exceptional versatility — striking enough for feature walls, gentle enough for full floors. Pair Onice with neutral cabinetry and warm wood for residential softness, or with matte black fixtures and brushed brass for a more architectural, contemporary statement.

Installation & Applications for Cerdomus Alma Onice 24×48 Matte

The 24″x48″ rectified format supports tight grout joints and a clean, modern installation. With an R10 slip rating (A+B class), the matte finish is approved for both interior and exterior floor applications — kitchens, bathrooms, mudrooms, foyers, patios, pool surrounds, and commercial floors. The rectified edges allow for tight grout joints down to 1/16″. Cross-coordinate with matching sizes and the polished finish for floor-to-wall continuity within the same Onice look.
