This custom porcelain pendant features the iconic neon-blue spots of the bluespotted ribbontail ray (Taeniura lymma). Scientists have found those blue dots are not pigments, but tiny nanoscale spheres loaded with guanine crystals and arranged in a “photonic glass” that reflects pure blue light—bright under any angle. A layer of melanin underneath makes the color even more intense . Researchers are studying this phenomenon to understand how structural colours work and how such vibrant blues are produced by natural nanostructures—insights that inspire eco-friendly colouring technologies . In my pendant, I first glazed the ray in soft blue and then applied gold, leaving the neon dots exposed—mirroring nature’s own play of structure and light. It was a fascinating blend of art and science! #bluespottedstingray #bluespottedrays #stingray #underwaterworld #marinebiology #artistjewellery #handmadejewellery #wearableart #contemporaryjewellery #pendant #goldjewelry
