To execute this classic look:

  1. Apply one thin, even coat of black gel polish over your cured base coat. Cure for 60 seconds.
  2. Apply a generous coat of emerald green cat eye gel polish over the black layer. Do not cure yet.
  3. Hold the rectangular magnet wand diagonally about 2–3 millimeters away from the nail surface at a 45-degree angle. Hold still for 5–10 seconds as the green magnetic particles cluster into a sharp, luminous line across the center.
  4. Flash-cure immediately under your LED lamp for 10 seconds to freeze the particle line before it diffuses.
  5. Complete the entire hand, cure fully for 60 seconds, and seal with a high-gloss non-wipe top coat.
