OB6303M features a refined stone texture that closely resembles natural marble, characterized by a calm, earthy grey-beige base tone with subtle warm undertones. Across the surface, the coloration is softly mottled, creating gentle transitions between light ash, taupe, and faint brown hues. Fine white and off-white veins run organically through the stone, appearing both as thin hairline cracks and slightly wider mineral streaks. These veins do not follow a strict direction; instead, they branch and intersect naturally, mimicking geological pressure patterns formed over time. Faint scratches and cloudy patches are visible beneath the surface pattern, suggesting natural wear or mineral layering, which adds to the realism and timeless quality of the material.
