A majestic unicorn with a radiant golden horn, surrounded by intricate, Celtic-inspired patterns and ornate designs. The unicorn's flowing mane and tail are adorned with swirling, iridescent blue and gold motifs, and its body is painted in a luminous combination of pearlescent white, 24-karat gold, and sky blue. The dark, velvety background accentuates the vibrant colors of the unicorn and the ornate details, with subtle, shimmering highlights on its coat. The unicorn appears to be in a serene, dreamlike environment, surrounded by delicate, pastel-hued flowers and other exquisite, Baroque-inspired decorative elements.
