Implantium™ is Smoothie London's standard for jewellery that works as hard as you do:
- Implant-grade titanium: ASTM F-136 - the same material grade used in medical implants, chosen for its exceptional biocompatibility and suitability for sensitive skin.
- Waterproof & tarnish-proof: wear it in the shower, at the gym, or on holiday without a second thought.
- No-poke comfort: our flatback design means you can sleep, train, and live in them 24/7.
Where most brands settle for stainless steel or mystery alloys, we raised the bar and created Implantium™: a new benchmark for piercing jewellery that’s stylish, and designed for everyday life.
Everyone's skin is different - if you're choosing jewellery for a fresh or healing piercing, we always recommend following your piercer's guidance.
8mm - Standard for lobes and most fresh piercings.
6mm - Snug fit for thinner cartilage placements (helix, tragus, flat). If your piercing is fully healed and you want a flush look, choose 6mm.
