**Nail Design Prompt**: Imagine a set of sleek black French tip nails, where the contrast between the crisp, dark edges and the natural nail base creates a striking visual effect. These tips are not your ordinary straight lines but feature an elegant, curved wave that adds a modern twist. To elevate the design, incorporate delicate silver foil accents along the black curve, giving the nails a hint of glamour and sophistication. The finishing touch is a glossy top coat that makes the nail art gleam under any light, enhancing the mystery and allure of the deep black shade.
