Abstract:

PURPOSE: To obtain a pierce mounting collar giving no damage to a through hole of an earlobe by a method wherein the collar is made of noble metal and formed in a cylinder having a flange part on one side.

CONSTITUTION: A cylindrical pierce mounting collar 2 made of noble metal and having a flange part 1 is engraved with screw thread 3 on its bore. As it is made of noble metal which will not corrode, the collar 2 gives no damage to a through hole. A setscrew 5 engraved at the tip end with male screw thread 4 corresponding to the female screw thread 3 on the bore of the collar 2 prevents the collar 2 from dropping off an earlobe together with the flange part 1. In addition, an accessory 7 engraved with a male screw thread 6 corresponding to the female screw thread 3 on the bore of the collar 2 is mounted on the tip end on the flange 1 side. In this constitution, many variations of couplings of pierces can be enjoyed.
