Imagine an elegant and sophisticated nail design featuring a deep, midnight-black base. This design is elevated with a touch of understated glamour, incorporating delicate silver lines and tiny sparkling rhinestones at the tips. Envision a subtle matte finish that enhances the black's allure, while the shimmer details catch the light. The overall design should feel both timeless and chic, perfect for an evening gala or a swanky night out. Let your imagination blend the beauty of classic with modern elements for a showcase-worthy design.
