Flowing Part Bezel set Marquise cut Diamond Solitaire Engagement Ring
Finalist in the CanadaMark engagement ring design competition
The 'Ursa' Engagement Ring is uniquely styled and exclusively available from Serendipity Diamonds. Choose your ideal ring combination from our menu to personalise the ring by Diamond size, whiteness and clarity in your chosen precious metal. This exquisite design is available in a choice of 950 Platinum, 18ct White Gold, 18ct Rose Gold, 18ct Yellow Gold and further Fairtrade Gold options. We have introduced this brand new Engagement Ring style to our collection after making a finalist in a national design competition in 2016 for the CanadaMark Diamond brand. The styling of this Marquise solitaire ring deviates from traditional styles. Held within a partial bezel setting, the Diamond rests diagonally within a flowing setting that sweeps seamlessly from a comfortable court shaped band. We handcraft each ring over four weeks through a time-honoured, traditional process merging the skills of casting, mounting, setting and finishing to arrive at the final commission, mirror polished to perfection. We deliver worldwide by secure delivery across the UK and Ireland, to Europe, USA, Canada and Australia. Each ring arrives beautifully packaged in a pristine white presentation box, accompanied by our complimentary pocket box, ideal for a surprise proposal. We include any tax and duty before payment for easy, no-hassle purchase, and we are happy to guide you through - from your initial enquiry through to the delivery of your finished commission.
Photographed in 100% ethical Fairtrade 18ct White Gold, the Ursa design reveals the impact of a diamond 0.80cts in weight.

Mount only and Starlight Moissanite ring options

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.
