Segment rings, also called seamless rings, give the appearance of a solid hoop going through a piercing. Like captive bead rings, these C-shaped hoops hold a closing segment in place using tension. The difference is that the closing segment in a seamless ring can move freely through the piercing, which may be more comfortable than a bead. Seamless rings with a thickness of 14 gauge or smaller can often be inserted yourself, while those thicker than a 14 gauge usually require a visit to a piercer with ring-expanding pliers.
Lather your hands with warm water and antibacterial soap and rinse them well. Repeat this procedure with your piercing. Use a fresh paper towel to dry your skin.
Dip one end of the open ring into water-based lubricant to help it slide through your piercing.
Align one side of the ring opening with your piercing and push it straight through horizontally. Rotate the ring so that the ring opening is on the outside of the piercing.
Grasp the bottom half of the ring, just below the opening, with your thumb and forefinger.
Seat one end of the closing segment on the bottom edge of the ring opening.
Push horizontally on the segment until the top indentation snaps into place with the top opening of the ring.
Always use freshly autoclaved body jewellery straight out of the autoclave bag. This is particularly important for new piercings.
Never insert a piece of jewellery that has been worn by someone else, no matter how clean the jewellery seems or how well you know the person.
