Product Description

Description

If you’re after a piece of body jewelry that truly stuns, look no further. This 4mm (¼-carat) VS1-clarity diamond labret radiates breathtaking brilliance — the kind that turns heads with every glance. Designed for those who love their sparkle to stand out, this large diamond shines brilliantly in cartilage piercings or lip piercings, catching light from every angle.

The martini prong setting keeps the diamond low and flush while still maximizing light exposure for extraordinary fire and shine. Each facet is expertly cut to enhance sparkle, glowing beautifully even in dim lighting. Paired with a flat-back disc for all-day comfort, this luxurious 14K gold labret is as practical as it is glamorous — a true show-stopper designed to last a lifetime.

  • 4mm (? 0.25 ct.) genuine, conflict-free diamond

  • VS1 Diamond Clarity – ideal brilliance

  • Martini prong setting | low-profile flush fit

  • Comfortable 3 mm flat-disc backing

  • Solid 14 K Gold | Nickel-free | Hypoallergenic

  • Commonly worn as a cartilage earring (helix, conch, tragus, earlobe) or lip ring (labret, Monroe, medusa, snake bites), and can even be styled as a nose stud

  • Ethically handmade in the USA
