River Stone series features a natural stone-inspired texture that feels grounded and authentic. Its design features a gentle mix of fine grains and mineral-like patterns that give it an earthy, unrefined appearance. Across the surface, subtle layers seem to merge and overlap, forming irregular patches that resemble naturally compacted stone. The grain structure is delicate yet visible, displaying a realistic stone formation effect that adds character and depth without appearing too bold or busy. The texture carries a balanced combination of smooth and slightly coarse areas, mimicking the look of naturally worn limestone.
