Take your freshly painted nails (pictured here is gold, but going with a gray, or white could look even better) and gently & carefully dip the tips of your nails into a jar of craft glitter. Alternatively depending upon the type of glitter you have on hand, you can also dust the glitter onto your nails, sprinkling them as you would a cupcake. After 3 min. apply a quick clear top coat.
