The negatively charged boron-vacancy pair - the BV$^-$ center - was a missing defect in diamond. It is expectedly very similar to the NV$^-$ center, which is one of the most famous spin defects or spin qubits in semiconductors. The BV$^-$ center has now been identified by electron paramagnetic resonance on specially prepared diamonds. Its spin-triplet state resembles a lot that of NV$^-$, while its optically detected magnetic resonance signal was invisible, posing a puzzle why the BV$^-$ luminescence is so weak.
