Black and White Harlequin Diamond Pattern

A seamless repeating pattern of tiny black and white harlequin diamonds arranged in a precise 12 × 12 grid within each repeating tile. The diamonds are all exactly the same size, slightly taller than they are wide, with perfectly uniform spacing and alignment. Orthographic top-down view, flat vector graphic, crisp clean lines, solid black and white colors only, no texture, no shadows, no gradients, no distortion, seamless repeat, high-resolution fabric and wallpaper pattern.
