PNM series features a calm, refined texture inspired by naturally weathered limestone and softly compacted mineral stone. Subtle tonal movement flows diagonally across the surface, created by faint, cloud-like shading variations. These gentle transitions echo the sedimentary layers found in natural stone, introducing a quiet sense of motion while maintaining overall cohesiveness. The marbling remains understated and delicate, appearing as soft diffusions rather than defined veins. Occasional speckling in slightly darker sandy hues adds depth and authenticity, preventing the surface from feeling flat or overly uniform. These fine inclusions feel organic, as if minerals were naturally embedded over time, reinforcing the stone-inspired character.
