White Rafaela granite
Also known as Gris Escorial, it is a light grey rock, of medium grain size and irregular fracture.
It is extracted in the province of Madrid, in the municipality of El Escorial. The blocks extracted are large in size and there are significant reserves.
Es un granito con colorita, moscovita, circón y opacos como minerales secundarios. Posee una textura granuda alotriomorfa.
It can be used for both interior and exterior cladding.
