Underwater Cave Enchanted Ring in Anime Style

An anime-style illustration of an enchanted ring resting on a smooth rock inside a dim underwater cave. The silver band is engraved with intricate cyan-blue runes that glow softly, casting a gentle glow on surrounding corals. The cave is alive with pale corals, kelp swaying with the current, and schools of tiny neon fish. Bioluminescent jellyfish drift by, leaving trailing halos of light. Beams of sunlight penetrate the water from above, carving bright shafts that illuminate bubbles, rock textures, and ancient glyphs on the walls. The composition is a close-up with a slightly low angle, high-detail linework, rich blues and teals, and a magical, serene atmosphere in anime style. Focus on the ring as the centerpiece, with shimmering water reflections and a sense of mystery.
