Create an enchanting underwater scene featuring a whimsical seahorse with intricate, gems jewellery-inspired designs. The seahorse should be adorned with vibrant, iridescent wings that shimmer in shades of blue, green, and purple. Surround it with a mystical ocean environment filled with coral reefs, bioluminescent plants, and gentle flowing currents. Add other magical elements, like magic shine and sparkling particles in the water, to enhance the otherworldly atmosphere. The overall mood should evoke a sense of wonder and exploration in a rich, colorful aquatic world.
