Deathly Hallows part 1 question?

i was watching the Deathly Hallows part 1 and when it got to the point where Hermoine, Ron, and Harry were trying to destroy Voldemorts locket it occurred to me that wouldnt they have been able to destroy it if they would have cast the cruciatus curse at it? cause i remember specifically reading in atleast one of the books that if you cast the torture curse at a "non-living" object it would just shatter the object to pieces.
