Available Lengths

  • 5mm — Ultra-short fit for thin lobes or tight, minimal movement.
  • 6.5mm (Standard) — Best for most healed piercings and everyday wear.

How to Measure:

  2. Add 1mm for comfortable clearance.
  3. Compare to Sinaury’s length chart above.

7. Comfort Tips

  • Choose flatback for 24/7 wear.
  • For sensitive skin, always select 14K solid gold.
  • Avoid overly long posts to prevent rotation or pressure.
  • Start with smaller stones for cartilage, larger ones for lobes.
