Blue Bleeding Heart Roseville Floor vase

Hi, I recently had an accident with a umbrella vase, and broke a corner piece off of the vase, of course we have re-attatched it, but have I now totally lost any value that the vase had prior? The vase usually lists for $700-$800. This is a huge accident and Im devistated, but what to do now? I would appreciate anyones opinion. Thank You
