Pictured at the left is an authentic Schwartz and Ablesser TCB necklace. Here are some tips from Lee Ableser for authenticating a Schwartz and Ablesser TCB: The chain has no breaks in it nor a clasp. The lest side of the chain connects to the outside top left of the "T". The chain is made of three small loops, connecting one section to the next. The right side of the chain connects to the outside top right of the "B". The front of the lightning bolt is not smooth, it is florentined. The back of the lightning bolt has "14K" stamped on it.
