A hyper-realistic portrait in 8K of a woman wearing a full mask sculpted from shimmering iridescent mother-of-pearl and frost, with delicate crystal formations branching symmetrically along the edges. She is adorned in a flowing gown of luminous moonlit blue and white silk, intricately embroidered with intricate frost-encrusted snowflake motifs, the fabric shimmering as if kissed by gossamer. The gown moves as if caught in a gentle, lunar breeze, creating an ethereal sense of motion. Her hair, a tumble of silken silver waves, glimmers softly, contrasting with her pale, alabaster-like skin that radiates a subtle, lunar frost-kissed glow. The background is a deep emerald green, a surreal contrast to the icy elements of her attire, creating a striking visual harmony that makes her luminous elegance stand out. Soft, silver-tinted lighting accentuates the delicate details of her mask and the luminous shimmer of her gown, enveloping her in an aura of ethereal beauty and mystery.
