The Cosima Halo Ring

About this design

A halo built through layers of detail

The Cosima surrounds its centre stone with a softened bezel, fine milgrain and bead-set detail. A closely set halo forms a scalloped perimeter, creating contrast between the calm line of the centre and the more textured frame around it.

Clustered stones extend into the shoulders in gentle fan-like formations, broadening the silhouette while keeping the head connected to a slender band. The low-set composition gives the ornament a grounded presence on the hand.

The centre stone can make The Cosima feel closely tonal or more richly contrasted. We consider its colour, cut and size against the bezel centre, scalloped halo and clustered shoulders so the layered detail remains clear.
