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.

Also, we offer most of our engagement rings with Moissanite instead of a diamond. This provides an ethical and affordable alternative to a natural or lab-grown diamond (also available) available across most of our ring styles. Look for the Starlight Moissanite or mount-only tabs, or contact us for a personal quote on any ring design.
