Design a nail art concept called "Bella Nails," inspired by the elegance and charm of a classic Italian Bella. Consider using a blend of soft blush pinks and creamy whites as a base, adding delicate floral patterns reminiscent of Tuscan gardens. Incorporate subtle gold leaf accents to evoke a sense of opulence. The overall design should be both timeless and graceful, echoing the beauty and sophistication of a vintage European summer. Add a modern twist with a matte finish to emphasize the detailed artwork and textures.
