Mystical Persian mermaid with ancient golden rhyton underwater

A mystical Persian mermaid in the depths of the Persian Gulf, with flowing emerald-green hair and a pearl crown of seashells and lotus flowers. She holds an ancient Achaemenid rhyton shaped like a winged lion (animal-shaped ceremonial drinking horn), richly detailed with gold, Persian royal engravings, Faravahar symbols, and Achaemenid relief patterns. The rhyton clearly has a horn-like form and a sculpted mythical lion body, not a vase. She studies it with reverence as a sacred relic from a lost Persian civilization. Surrounding her are drifting sea plants and coral reefs, with sun rays filtering through deep blue water. Close-up cinematic underwater fantasy portrait, ultra-detailed digital painting, turquoise and sapphire tones, ethereal atmosphere.
