Inside an enormous cave made entirely of multicolored crystals, the vast space glows with a magical and ethereal atmosphere. The crystals, in varying sizes, radiate a clear, luminous light, reflecting and refracting countless iridescent hues inspired by the delicate tones of an opal--soft blues, pastel pinks, vivid greens, and shimmering purples. Light dances across the surfaces, creating dazzling patterns of brilliance that illuminate the cavern. The intricate crystalline formations stretch across walls, ceiling, and floor, filling the space with an awe-inspiring sense of grandeur. The scene is photorealistic, capturing every fine detail, from the textures of the crystals to the soft glow that permeates the air, evoking a sense of wonder and otherworldly beauty. --ar 16:9
