Designed to move with you, not irritate you.
This marquise drop flatback is crafted in Implantium™ - our medical-grade titanium chosen for its biocompatibility, smoothness and long-term comfort. The floating crystal catches the light subtly as you move, giving that “just enough” sparkle without ever feeling fussy.
Engineered for everyday wear, the flatback sits flush against the ear, making it comfortable to sleep in, shower in and forget you’re even wearing. Elegant enough to elevate a curated ear stack, practical enough for real life.

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.
