Create an exquisite nail design that radiates opulence and magnetism. The nails should sport an ombre effect transitioning from a deep, mysterious black to a radiant gold tip. Add intricate metallic swirls weaving through the colors with delicate rhinestone embellishments for extra flair. Against this magnetic backdrop, sprinkle microglitter to enhance the glamorous effect under different lighting. Finish with a glossy top coat to seal the glamnetic look.
