Midnight Boulder Nano Stone
WIO Midnight Boulder Nano Stone, Raw texture, ancient character, and sculptural presence to your scapes-dark volcanic stones with irregular forms and detailed surfaces, perfectly scaled for mossy, aged layouts in compact spaces.
WIO Midnight Boulder Nano Stone is a richly textured igneous stone, naturally formed with holes, crevices, and worn surfaces that evoke the feeling of primordial landscapes. Its deep, dark tones-ranging from charcoal to black-create a powerful contrast in naturalistic designs, offering the look of ancient relics shaped by time and the elements.
