The Trachyte quarries of Sardinia, Italy were the inspiration behind Coem's new collection, Pietre di Gallura. The series comes in five sizes (61-by-61 cm, 30.5-by-61 cm, 30.5-by-30.5 cm, 45.8-by-45.8 cm, and 22.9-by-45.8 cm) and four colors (Ivory, Grey, Walnut, and Wild Rose). The line is complemented by artistic ceramic decorations in deep and varied shades of blue, embedded like gems in the stone.
