Mount only and Starlight Moissanite ring options

We now provide most of our ring styles in two further choices. Firstly, we create finished ring mounts available for your own diamonds or gemstones. In addition, we provide a range of add-on services, including stone setting and inward insurance, to cover items sent to us for setting. 

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.
