Blanco Alconera Marble (Alconera White)

Origin: Spain – Alconera, Province of Badajoz

General Description

Blanco Alconera Marble, also known as Alconera White, is a timeless Spanish marble characterized by its whitish base tone with great ornamental variety, ranging from areas of homogeneity to capricious veining with subtle traces of gray, beige, and warmer hues. Its versatility, clarity, and excellent technical performance make it highly sought after for both interior and exterior architectural projects.

The stone is available in multiple surface finishes — polished, honed, satin, brushed, sanded, tumbled, flamed, and sandblasted — allowing applications from luxury interiors to high-traffic outdoor spaces.
