Envision a set of nails that captures the ethereal beauty of sparkling crystals, where each nail mirrors the multifaceted shimmer of gemstones under sunlight. The base color should be a soft, translucent white to imitate clear quartz, adorned with iridescent flakes that change color with every movement. Add delicate accents of fine silver lines that suggest intricate crystal veins. To complete the design, integrate small, strategically placed crystal decals for an authentic, luxurious touch. Imagine the design exuding an aura that is both mystical and elegant, reminiscent of a sacred treasure.
