Unusual Two Stone Diamond Open Engagement Ring

The 'Flow' ring design has been styled with a fluid form, effortlessly embracing two beautifully cut Round Brilliant Diamonds. Choose from two variations. Our featured 0.60cts version (shown above) has been handset with 4.5mm (0.35cts) and 4mm (0.25cts) Diamonds. Alternatively the 0.26cts version is available set with 3.5mm (0.16cts) and 3mm (0.10cts) Diamonds. We craft each ring using the finest natural Round Brilliant cut Diamonds, graded G Colour and SI1 Clarity for brilliant whiteness and exceptional clarity. We provide a further service to craft a bespoke shaped wedding ring to this design, ensuring a perfect fit.

Choosing the wedding ring 

Whether you choose a complete band, or a split band, we can create a truly unique wedding ring design as part of our bespoke wedding ring service. Please allow additional time if you wish to commission both the engagement ring and wedding ring at the same time.

A unique engagement ring deserves and unique wedding ring. This is exactly what we created as one choice of wedding ring to match the Flow engagement ring design. We set out to design a wedding ring styled to complement the curvature and elegance of the engagement ring design. A split band design allows tapering shoulders to curve into the ring for a truly individual look. In stark contrast to the traditional full-band wedding ring works beautifully with the unique setting of the Flow design. 

Responsibly sourced precious metals and Fairtrade Gold

An important part of our work involves the use of responsibly sourced precious metals and gemstones. As such, we only work with re-cycled, ethically sourced Gold, Platinum and Silver. In addition, we offer the option of Fairtrade Gold across most of our jewellery designs available upon request. 

How does my engagement ring arrive?

Within the United Kingdom, each completed ring from our extensive diamond engagement ring collection is beautifully packaged and sent by International Signed For Delivery, by Royal Mail. We insure all parcels until they arrive with you. 

Deliveries arrive the next day after despatch. All parcels arrive under plain wrapping. Inside you will discover a sturdy outer box containing a document section with a document folder for valuations and certification.

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.
