Popis:	The piezoelectric sensitivities of 20 z‐cut tourmaline crystals have been compared up to 7 kbar. Deviations from a mean of up to 15% have been found. The mean was 1.69×10−8 C/cm2·kbar for uniaxial and 2.39×10−8 C/cm2·kbar for triaxial tests to 3.5 kbar. A quadratic was fitted to sensitivities obtained from shocking the crystals to 7 kbar. Another set of crystals of different size was compared to the first. Fair agreement was found at high pressures, poor agreement at low. Hysteresis was not observed, nor was directional dependence.
