GRAMABLACK – CALATORAO STONE
The Calatorao Stone is a marble limestone dated back to the Jurassic period (more than 170 million years ago) quarried in the Dehesa Boyal del Romeral, located in the village of Calatorao and it is sourced from our own quarries in the heart of Aragón (Spain).
Its excellent crystallisation grade and singular colour tone make it a unique stone, both for its aesthetic properties and for its strength and durability. The polishing of the pieces enhances their intense black glossiness which giving them the name of Black Marble from Calatorao.
At GRAMABLACK we are design specialists and we conceive each of our pieces from the strength of the land that saw them born; the history and time involved in their creation process; and the quality of our dedication and hard work. We produce our products from the natural stone´s extraction and we manage the comprehensive manufacturing service with the intention of achieving the most exclusive pieces of black marble.
Our stone is unique. Its black colour, its slightly veined texture and the unique fossils presence make Calatorao stone a beautiful product itself, capable of adding distinction and elegance to every project. In addition to its aesthetic appeal, its natural quality has been recognised by quality certificates such as CE Marking, which make our products highly desired pieces by every architecture, landscape and interior design professional.
