A grand staircase made of translucent turquoise glass spirals upward from the depths of a vibrant coral sea. The staircase is illuminated by soft, diffused light filtering from the surface. Coral formations in vivid shades of red, orange, and pink grow along the sides of the staircase, blending seamlessly with the turquoise glass. Marine creatures, including fish, jellyfish, and sea turtles, are made of coral and translucent turquoise glass, swimming gracefully alongside the staircase. The creatures reflect light, casting ethereal shadows onto the stairway. The surface above is a surreal blend of sky and sea, with soft clouds merging into the water, creating a seamless horizon. The overall scene is photorealistic with intricate details, including the texture of the coral, the smoothness of the glass, and the subtle ripples in the water. The lighting is soft but striking, emphasizing the contrast between the warm coral tones and the cool turquoise glass. The perspective is from below, looking up the staircase toward the surface, with the marine creatures leading the eye upward
