Abstract: It is an object of the present invention to provide a jewel which can be securely attached to a string-form member or pedestal with a stable frictional force, and which can be easily removed from such a string-form member or pedestal. The base body has a hole, and the hole opens at the surface of the base body. The elastic body has a through-hole, and is inserted into the interior of the hole. At least one open end of the through-hole communicates with the outside of the base body via the hole, and the internal diameter of the through-hole is gradually expanded toward the abovementioned open end.
