Iridescent Oyster Shell Nacre on Lichen Bark

Cool dawn light falls through dust motes, illuminating the microscopic layers of an oyster shell's nacre. The shell rests on rough, lichen-covered bark, its surface shimmering with blues, greens, and soft pinks. Fine dust particles float in the backlight, creating a hazy glow around the subject. The texture of the bark contrasts with the smooth, iridescent curves of the shell. Negative space surrounds the object, emphasizing its delicate structure against the organic, earthy tones of the lichen. The light catches the edges of the shell, revealing the intricate, layered pattern of the nacre. One ray of light highlights the subtle gradient of colors within the shell's interior.
