Cosima Diamond Band

This half-eternity ring brings diamond detail across part of the band, creating a romantic focal point within a timeless ring style. The 3 mm band gives the design its own proportions.

Wear it as a meaningful piece on its own, or explore it alongside your other rings to find a combination that feels personal.
