  • Patent number: 5946943
    Abstract: Jewelry for insertion through the bore of a body part piercing. The jewelry comprises a crescent-shaped body of a memory resilient material having terminal ends adapted to be inserted within a piercing. A concave depression is defined on an inner side of one of the terminal ends. A second body such as a ball bearing is insertable between the terminal ends and is firmly seated within the concave depression to clasp the jewelry within the piercing. The ball bearing has a diameter slightly greater than a distance between the terminal ends of the crescent-shaped body to first force the terminal ends apart and then create an inwardly directed biasing force against the second body when the ball bearing is inserted therebetween, thus firmly holding the ball bearing within the concave depression and between the terminal ends.
