I had always understood this to be a reward (presumably in the bag of fishing treasures) for doing one of the Dalaran fishing quests.
However, last week, my hubby reported to me an unusual method of acquisition. He had called up one of his characters (a 74 night elf hunter) and went to do the Ghost Fish quest. About to cast, he discovered that - no doubt in some pack clearing frenzy - he had sold her moderately good pole. He took the character back to Marcia and picked up whatever she had there in the line of poles and returned to Sholazar to fish. On his second cast, he CAUGHT a jeweled fishing pole! ... along with a fish. He doesn't remember whether it was a nettlefish or a goby because he was so surprised by the pole.
I've seen the pole - sweet - but didn't see his character catch this lovely pole. Then, again, I have no reason to think he fabricated its provenance.
Any one else CATCH a Jeweled or Bone fishing pole?
