  1. We demonstrate the operation of a rotation sensor based on the nitrogen-14 ( 14 N) nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor uses optical polarization and readout of the nuclei and a radio-frequency double-quantum pulse protocol that monitors 14 N nuclear spin precession. This measurement protocol suppresses the sensitivity to temperature variations in the 14 N quadrupole splitting, and it does not require microwave pulses resonant with the NV electron spin transitions. The device was tested on a rotation platform and demonstrated a sensitivity of 4.7°/ s (13 mHz/ Hz ), with a bias stability of 0.4 °/s (1.1 mHz).
