💎 The Detail
Simple, sparkling and easy to style, this crystal flat-back stud works beautifully as a delicate accent in helix, flat, conch and lobe piercings. Its compact crystal top also makes it easy to combine with decorative studs and hoops in a curated ear.
The 16G post has an 8mm wearable length and an externally threaded crystal end. Because exposed external threads pass through the piercing during insertion, fit and remove the jewellery carefully and reserve it for fully healed piercings.
Each colour has a PVD finish. Avoid prolonged contact with water, sweat, perfume, lotions and household chemicals to help preserve the coating. Clean gently with a soft cloth and store somewhere clean and dry when it is not being worn.
