Create a mesmerizing set of aura nails that radiate vibrant energy and ethereal charm. Use a gradient blend of soft pastel colors melting into bold, jewel-toned hues, reflecting the transitional beauty of an aura. Incorporate subtle glimmers and hints of iridescent shimmer to mimic a celestial glow. Let each nail exude a unique spectrum, yet together form a harmonious balance, akin to the natural energy fields.
