if its certain skills for certain jewelry You would have to write the script or modify a bracelet script for instance if You want a bracelet with hitpoint increase ,, mana increase ect ect , if Your adding stuff to any bracelet that drops in loot then I believe that would be adding clips to each piece of jewelry but doin it that way any mob that drops the stock modified jewelry will drop it meaning instead of having a custom mob drop specific jewelry any mob would drop it overrunning shard with it ,, hope this helps and hope I understood what You was asking
