Unity Diamond Engagement Ring

Unity reveals the dramatic beauty of a modern Round Brilliant cut Diamond. Deceptively simple styling exposes the detail of all 57 Diamond facets. Tensioned between each side of the setting, the Diamond is open to the passage of light – revealing brilliance and scintillation. Embraced by elegantly contoured shoulders the Diamond rests above a comfortable court shaped band. Once you have chosen your precious metal and Diamond options, we will create the perfect Diamond engagement ring for you, meticulously crafting your commission over 4 weeks. The ring will arrive impeccably presented in bespoke packaging – arriving by secure courier, fully insured to your door.  

Photographs below show the Unity engagement ring - Platinum 0.50 carats, 0.80 carats, and finally 1.20 carats. 

Choosing a wedding ring for the Unity design

When the time comes for you to choose a wedding ring, we can create a bespoke design to flow around the graceful curves of the Unity design. Choose from a plain or diamond set shaped wedding ring from our bespoke shaped wedding ring service. We will create the perfect shaped wedding ring for you working with the original engagement ring. If you are based overseas, talk to us about commissioning the advance shaped wedding ring model which we can hold on file until a later date ready to create the wedding ring ahead of the big day.
