1. Apply a sheer, nude-to-skin-tone base coat across the nail plate and cure.
  2. Place geometric nail vinyls or striping tape across the center of the nail to block off a crisp diagonal section or diamond cutout.
  3. Paint the exposed outer zones using pitch-black gel polish, followed by emerald cat eye gel.
  4. Hover your magnet wand along the edges of the tape lines to draw the magnetic shimmer right up to the crisp border lines.
  5. Carefully peel away the striping tape while the gel is still wet to reveal clean negative space underneath. Cure for 60 seconds and apply top coat.
