Moonstone is a series inspired by Pierre Bleue Belge, a stone with a color ranging from blue gray to black gray characterized by the presence of numerous marine fossil residues. This graphic develops on the surface, reminding us of the unstoppable force of time that passes and changes the material, giving it even more strength and consistency. We developed the series to offer an emotion of natural materiality that can be expressed in all environments, from inside to outside, thanks to the various formats, thicknesses, special pieces and decorations.
