MORE ON THE IVORY POMEGRANATE FORGERY: Today's A.P. article has some additional information on how the forgery was detected (my emphasis):
Snyder said the pomegranate was examined by several scholars before and after the purchase and was authenticated for the museum by Israeli archaeologist Nahman Avigad.

The director said the pomegranate was examined with the technologies available at the time. "I think care was taken," Snyder said. "If one does not take advantage of opportunities to bring into a museum setting objects that don't surface in excavations, you might miss great objects."

He said the pomegranate was re-examined with a new type of microscope that detected synthetic material in the inscription, between the ivory and the patina.

The museum said another ancient object displayed with the pomegranate, a 2,600-year-old silver amulet with a priestly blessing carved into it, was re-examined and deemed authentic.

The Ketef Hinnom silver amulets were scientifically excavated, so I don't doubt that they are authentic.

As for the pomegranate and other forgeries, I'm struck by how the forgers often seem to be some years inside the scholarly response cycle. In other words, the forgers can produce forgeries that are undetectable by the best current methods of evaluation, but the forgeries are uncovered not too many years later by new technologies unknown to the forgers or the original autheticators. I doubt the forgers care; they've already safely made their sale and crawled back into the woodwork.

I don't know if there's a solution to this problem. It may be that a century from now forgers will be producing undetectably forged first-century scrolls using nanoreplicators that deposit just the right number of C-14 atoms into the manufactured parchments to make them appear ancient, and it will only be ten or twenty years later that scholars will use the new Berry-phase data-recovery technology to detect that the quantum entanglements of the forged scrolls are all from the twenty-second century.
