Grey Unum Ring


The Unum Ring is part of our collection of placeholder rings – temporarily taking the place of an engagement ring. It allows the couple to choose a design or create a bespoke piece together once the proposal has taken place. They become treasured pieces of jewellery in their own right, wearable on another finger after a more formal engagement ring is made, as a keepsake of each couple’s love story.

The Unum Ring features a small grey round diamond inset into a D-shape band.
