Del Castillo Gray
DESCRIPTION
Del Castillo Gray comes from Spain’s oldest operating quarry dating back to the 16th century. The stone is Bernardos phyllite which the International Union of Geological Sciences named as a “Heritage Stone” in 2022.
Del Castillo Gray is a refined phyllite slate quarried near Segovia, Spain. It has a medium gray tone with silver/blue undertones, sourced from a single origin quarry with roots dating back to the 1500s. Offered in 7–8 mm and 8–10 mm thicknesses, it’s robust yet elegant, suitable for both roofing and interior applications
