Captive bead ring

The captive bead or ball fits into a small opening in the circle of the ring.

It uses the natural tensile or compressive strength of the metal the ring is made of, usually surgical stainless steel, niobium, or titanium, to hold the bead tightly in place.

The bead or ball itself may additionally be made from coloured glass, acrylic or ceramic, or a gemstone.

This is a popular piece of body jewelry because it conveniently allows the wearer to remove the ring by simply removing the captive bead; the bead is held firmly in place so that it will not easily fall out.

Additionally, because of their closed shape and rounded edges, these rings do not easily snag on clothing, hair, or furniture, making them a popular choice for piercings which are still healing.
