Nitrogen‐vacancy (NV) colour centre in diamond is a very promising tool for sensing applications from magnetometry to thermometry. In this paper, we demonstrate a compact and convenient device for magnetic‐field sensing where a commercial single‐mode photonic crystal fibre is directly coupled to a commercial high quality diamond sample synthesised by means of chemical vapour deposition process and containing a residual nitrogen impurity rate smaller than 1 part per million. We managed to excite and detect efficiently the photoluminescence from an ensemble of NV centres and to perform electron spin resonance experiments where the NV hyperfine structure is perfectly resolved under continuous measurement.
