We demonstrate a nuclear magnetic resonance gyroscope based on the 14N nuclear spins intrinsic to nitrogen-vacancy (NV) centers in diamond. Nuclear spins were polarized and readout optically, without the use of microwave transitions [1]. We used double-quantum nuclear Ramsey technique that increases sensitivity to rotations while suppressing the effect of thermal drifts. The device was mounted on a rotation platform and faithfully reported rotation rates in the range of 5-500 mHz. Significant progress can be expected by switching to bulk 13C nuclear spins in the diamond crystal that will be optically polarized via NV centers.
