Feast your eyes on fall's must-have manis.

You've tried crackle topcoats and mastered the half-moon mani. Now, check out the latest nail art trends that will make everyone do double-takes:

It's magnetic. New polish from brands including LCN (pictured) and Layla contain tiny magnetized particles. Hold a magnet above wet polish for 10 seconds to attract the particles and pull them into a design, leaving you with an airbrushed effect. Watch a video demo here. 

Oh my ombré. Stars such as Lauren Conrad have been spotted with this multi-hued look. (Check out photos here.) See step-by-step instructions and video here. 

Good as gold. Be-leaf it! Ripped from the 3.1 Philip Lim and Monique Lhuillier runways, CND's Sheer 24K Sparkle Effect makes nails look like they've been dipped in gold lamé. Buy here.

We've got your digits.
