Humorous jewelry is a great icebreaker that can lead to increased sales. Really unusual pieces-such as Rembrandt’s false teeth and vasectomy charms and Links of London’s Tits ‘n’ Bums cuff-links-stop people in their tracks.

Quite often, inspiration for silly pieces comes from customers, according to Rembrandt Quality Charms, Buffalo, N.Y. “Our vasectomy charm is a wonderful conversation piece for a urologist to wear,” says RQC president Chris Lux. The company also makes a toilet seat charm but doesn’t have any suggestions as to who might wear that one.
