No. 003 Engagement Ring

Bosona

Pure geometry in a minimalist form: the Bosona engagement ring sets an emerald-cut stone into a smooth bezel setting that protects it all the way around. The delicate, rounded band lets the lines of the stone stand out, and carries the Sirius collection’s star on the underside.

On request, we can adjust the piece to your specification – for example the diamond size, cut or other details.
