It has become extremely obvious to me lately, as I have been working on the doors of my house, that gravity bends and warps things. It would seem that = a quartz crystal is no different. Stress is applied, no matter how slight. I would expect such stress to influence the resonance of the crystal. I.e. Change the stress =3D change the resonance.
