Actually, frequency DOES make a difference.  At much lower
frequencies (like 500 KHz and below), the mass of the resonator is
high enough to make it very sensitive to shock and vibration.  At 10
MHz, though, the resonator's pretty small and, therefore, resistant
to damage.

Consult the manufacturer's data sheets for your particular
resonator's vibration specs.
