Diamond Icebergs Beneath Viridian and Violet Aurora Bands

Full prompt

Astrophotography landscape at Jökulsárlón glacier lagoon in southeastern Iceland. Luminous ribbons of viridian green and soft violet aurora weave dynamically across the dark blue zenith, punctuated by the faint glow of the Milky Way. In the foreground, crystalline stranded icebergs on black volcanic sands glisten like faceted gemstones, refracting the cool auroral light across their translucent edges. Calving ice floes drift silently on the sheltered lagoon waters, rippling with iridescent green reflections. The low horizon reveals the silhouette of the distant Vatnajökull ice cap under a crisp winter atmosphere. Captured with long-exposure photography, preserving sharp stellar points, glass-like ice textures, and natural saturation gradations.
