Iridescent Oyster Shell Nacre Layers in Wenzhou Pod

Pale green fluorescent light cuts through predawn darkness to illuminate the split interior of a seed pod resting on a sterile white surface. Inside the hollow cavity, an oyster shell fragment displays thick, layered nacre with jewel-like precision. The surfaces gleam with sharp reflections of blues, greens, and purples that shift across the curved ridges. Clean edges define the organic curves against the stark, empty negative space surrounding the specimen. The texture appears smooth yet deeply grooved, catching the overhead glare in narrow, bright lines. A final shadow falls along the bottom edge of the shell, at the base of the iridescent layers against the matte interior of the pod.
