Corrin
Corrin is the core motif found at the heart of vitamin B12. Its beauty lies in a strikingly asymmetric structure: the left side of the ring is missing some of the double bonds present on the right, and one of the bridging carbons is absent altogether. The name itself comes from this central role, derived from the core of vitamin B12.
In these earrings, the pearl at the center stands in for cobalt, the essential metal that sits cradled inside every corrin ring in nature. The surrounding silverwork traces the molecule's quietly uneven shape, a reminder that not all symmetry in chemistry is perfect, and that the asymmetry itself is part of what makes vitamin B12 work.
