Craft a dazzling nail design that combines the elegance of black with the opulence of gold. Start each nail with a sleek black base, and embellish with striking gold accents—think delicate lines, geometric shapes, or shimmering foil. Introduce a playful contrast by adding matte, glossy, or glitter finishes to different nails. Consider incorporating elements like gold foil tips, intricate gold patterns, or chic black-and-gold ombre effects. This design should exude luxury and glamour, perfect for a sophisticated evening or a lavish celebration.
