Piercing jewelry standards

The creation of piercing jewelry is far more complex than that of a simple earrings. It took us several months of development work to bring you perfectly adapted jewelry that meets the highest standards expected by Association of Professional Piercers. We use traditional jewelry techniques and combine new technologies as 3D printing to obtain jewelry with a precision to the tenth of a millimeter.

  • Our jewelry thickness (1.2mm or 1.6mm depending on piercing) is standard, allowing you to change freely from a piercing to another piercing anytime you want to.
  • We don’t use external threading for our closure system.
  • Our 3 colors of 18k gold are nickel and cadmium free, and hypoallergenic.
  • Our jewelry is handmade mirror polished.

You can safely use our jewelry on healed piercing. If you are considering getting pierced with our jewelry, please consult your piercer first.


We only use flat back labret jewelry for our piercing studs. The flat back sits flush against the skin, reducing irritation and discomfort compared to other types of jewelry with protruding ends or shapes. Also, it minimizes the chances of accidental injuries or trauma caused by jewelry catching on clothing or getting snagged.

Internally threaded jewelry

Our piercing studs are available with an internally threaded labret or barbell for backing. This design meets the highest standards in piercing. Unlike externally threaded jewelry that can cause damage to the tissue, internally threaded jewelry labret or barbell are super smooth and the threading comes off of the piercing end.

Our threaded pin are in platinium.

Clicker rings

Our piercing rings feature a hinge mechanism with clicker closure.

To open: Grasp the top clasp while holding the clicker ring. Gently pull on the end of the clasp to open it.

To close (wear and secure): Place the clasp through the desired piercing in the ear. Next, align the clasp with the gap of the clicker ring. Press the hinge pin vertically to close the ring. The earring will be fastened once a *click* is heard. Be careful not to misalign the ring.
