Sterling silver center crimp cord ends with a hook make it easy to finish the ends of your jewelry cord. Simply pair a 925 silver center crimp hook with a 925 silver center crimp loop to add a full hook and eye clasp to your necklace and bracelet designs! Sterling silver is a noble metal (a.k. precious metal) and is therefore a great choice for higher end jewelry. These silver jewelry findings will naturally tarnish over time.
