To help you find the right size replacement part, always measure the actual prism length and do not include the top bead. So if your prisms or pendalogues measure 4"e;(not including top bead) then you should look for a 4"e; prism with a similiar shape. The prism bead or jewel head along with the head pin add approximately 1/2"e; to 3/4"e; to the stated prism length.
