The claw, talon or pincher is essentially a curved taper which is worn in stretched ear lobe piercings. The thickest end is generally flared and may be decorated, and a rubber o-ring may also be used to prevent the talon from becoming dislodged when worn. Common materials include acrylic and glass. A similar item of jewelry is the crescent, or pincher, which as the name suggests, is shaped like a crescent moon and is tapered at both ends. Talons and claws may also be quite ornamental (e.g.: carved in the form of a serpent or dragon). Consequently, they may prove to be an impractical choice of jewelry as they may snag on hair, clothing, etc.
