As a colour on its own. Apply over the whole nail in the usual way.

Alternatively ..

Diamond French Manicure. Apply a coat of DIAMOND ICE roughly onto the nail tip. Paint the polish horizontally across the width of the nail, ideally on one smooth sweep. Don't worry if the white is not tidy as you can shape it with the Leighton Denny PRECISION CORRECTOR SET. Dip the brush into the liquid then use like an eraser to wipe away the excess white and make a gentle curve. Wipe the brush on a tissue between each use to keep it clean. When dry apply DIAMOND ROSE or DIAMOND IVORY over the whole nail including the tip. To seal, protect and help extend wear, apply a coat of CRYSTAL FINISH over the entire nail
